get_object_vars

(PHP 4, PHP 5)

get_object_varsВозвращает свойства указанного объекта

Описание

array get_object_vars ( object $object )

Возвращает видимые нестатические свойства указанного объекта object в соответствии с областью видимости.

Список параметров

object

Экземпляр объекта

Возвращаемые значения

Возвращает ассоциативный массив нестатических свойств объекта object, доступных в данной области видимости. Если свойству не было присвоено значение, оно будет возвращено со значением NULL.

Список изменений

Версия Описание
5.3.0 Функция теперь возвращает NULL, если object не является объектом. Ранее возвращался FALSE.
4.2.0 Свойства, которые были объявлены в классе объекта object, но которым не были присвоены значения, теперь также возвращаются (со значением NULL).

Примеры

Пример #1 Пример использования get_object_vars()

<?php

class foo {
    private 
$a;
    public 
$b 1;
    public 
$c;
    private 
$d;
    static 
$e;

    public function 
test() {
        
var_dump(get_object_vars($this));
    }
}

$test = new foo;
var_dump(get_object_vars($test));

$test->test();

?>

Результат выполнения данного примера:

array(2) {
  ["b"]=>
  int(1)
  ["c"]=>
  NULL
}
array(4) {
  ["a"]=>
  NULL
  ["b"]=>
  int(1)
  ["c"]=>
  NULL
  ["d"]=>
  NULL
}

There is a strange behaviour, not sure whether it is a bug:

if I call
<?
$single_object 
$data_array_of_objects[0];
$array_of_objectvars get_object_vars($single_object);
     foreach(
$array_of_objectvars as $key => $val) {
     echo(
" $key => $val<br>");
     }
?>
I get only _ONE_ line with the $key = first variable name of the object and $val = the values of _ALL_ variables of the object including the first separated by a space.

NOW:
if I call
<?
$single_object 
$data_array_of_objects[0];
$array_of_objectvars get_object_vars($single_object);
     foreach(
$array_of_objectvars as $key => $val) {
     echo(
" $key => $val<br>");
     }
     echo(
$data_array_of_objects[0]->objectvar1."<br>");
     echo(
$data_array_of_objects[0]->objectvar2."<br>");
?>

I get a list of $key = $ val as expected, before the other echos' are printed.
It seems to me that get_object_vars works differently when you access a variable in those objects explicitly (as in the echos)

It seems that get_object_vars will now return properties of an object even if they have no value  - meaning only defined by var $foo in the class declaration.  This is noted behaviour in 4.2.1 which is different from previous versions and hitherto undocumented on this page.

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
Furthermore, variables not declared in the class but set on a given object, will be returned by get_object_vars().

Example, ver. 4.2.1:
<?
class MyTest {
        var 
$classVar1 'Class Var 1';
        var 
$classVar2;
        var 
$classVar3;

        function 
MyTest()
        {
               
$this->classVar2 'class var 2';
        }
}

$test = new MyTest();
// This var isn't declared in the class
$test->newObjVar 'foobar';

echo 
"<pre>";
print_r(get_object_vars($test));
echo 
"</pre>";
?>

The output is:
Array
(

    [classVar1] => Class Var 1
    [classVar2] => class var 2
    [classVar3] => 
    [newObjVar] => foobar
)

Prior to version 4.2, classVar3 would not be output as it was never assigned a value.

In case your object contains again objects (and so on), this function might be useful:

function makeAssoc($res) {
  $res = get_object_vars($res);
  while (list($key, $value) = each($res)) {
    if (is_object($value)) {
      $res[$key] = makeAssoc($value);
    }
  }
  return $res;
}

hello,

this example will look like all values of vars was set in your class. write a method like the name: dumpClass and then fill in follow code:

$vars = get_object_vars($this);

echo "<b>class vars</b>";

foreach( $vars as $name => $value ) {
    echo "<li>".$name." : ".$value;
}

look at: get_object_vars($this);

Hi,

I figured out that in prior version to 4.2 the returned array only contains attributes directly in this class, excluding the derived ones from parentclasses.

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
In case your object contains again OBJECTS or ARRAYS:

function makeAssoc($res) {
  if (is_object($res)) $res = get_object_vars($res);
  while (list($key, $value) = each($res)) {
    if (is_object($value) || is_array($value)) {
      $res[$key] = makeAssoc($value);
    }
  }
  return $res;
}

Please note that you cannot affect the object via the array values...in other words, the returned array does not contain references to the values within the object, but copies.

If you are making an object inspector or editor, this is not good enough.  So I made the following methods:

METHODS:

function &getVar($obj, $name)
{
        $expr="\$prop=&\$obj->$name;";
        eval($expr);
        return $prop;
}

function &getObjectVars($obj)
{
        $result=array();
        $vars=get_object_vars($obj);
        foreach ($vars as $var => $value)
        {
                $result[$var]=&getVar(&$obj, $var);
        }
        return $result;
}

[NOTE:  You must pass in a reference to an object, not an object.  Sorry if this  offends PHP'ers, but the distinction of pass-by-value and copy-on-assignment drives me batty (compared to Python, Java, Smalltalk), so I make all my functions pass by value, and force myself to pass in a reference to keep track of what is happening under the hood.]

EXAMPLE:

class Bob
{
        function Bob()
        {
                $this->thing=13;
                $this->other="whatever";
        }

        var $thing;
        var $other;
}

$obj=&new Bob();

# NOTE:  Passing in a reference!
$props=getObjectVars(&$obj);
$props["thing"]=-11;

var_dump($obj);

RESULTS:

object(bob)(2) {
  ["thing"]=>
  &int(-11)
  ["other"]=>
  &string(8) "whatever"
}

Hmmm.  A bit embarassing...

It turns out the best way to get references to all of your objects member variables is NOT with the functions I provided before, or with get_object_vars.

Just cast the object to array.

$a=(array)$obj;

# The two following statements are now equivalent and identical
$a["member"]=3;
$obj->member=3;

A very powerful tool, for inspectors and what not.

more strange, strange behaviour: 

if you are trying to deep-copy an object with get_object_vars(), strange behaviour can accidentally clobber your original object properties.  please read very, very carefully: 

get_object_vars() may either return references to *or* deep copies of the object's properties *depending on whether that property has been set with the -> operator*.   (this behaviour probably varies per php platform and os so please confirm for yourself.) 

furthermore, consider 
  $properties = get_object_vars($obj);
normally, unset()ting a reference does not affect the original, i.e. $ref = NULL; is not the same as unset($ref); per the references documentation.  However, if you have this strange references version and you unset() an array element of $properties, it will *SET THE OBJECT PROPERTY TO NULL*, which is not how references normally work. 

even stranger behaviour comes into effect that i can only express with an example.  please test this with your version and OS and proceed very carefully:
-->
<?php
echo "<pre>\n";

class 
Lump
{
   var 
$size 'average';

   function & 
copy()
   { 
// return a deep copy
     
$copy = new Lump();   
     
$properties get_object_vars($this);
      foreach( 
array_keys$properties ) as $property ){
         
$copy->$property $properties[$property];  // deep, right?
     
}
      return 
$copy;
   } 

}

$lump = new Lump();

$lump->size 'huge'// <--- this line changes everything
// comment above line out, and see the difference
// also, try substituting another property for 'size'

$properties get_object_vars($lump);
$properties['size'] = 'small'// this behavior varies

echo "after changing the properties array:\n";
var_dump$lump ); 
// it's either big or small (never huge) depending on 
// whether you commented-out the indicated line

//------------- let's try using our copy() method

$original_lump = new Lump();
$original_lump->size 'huge'// this line changes the behaviour
$other_lump =& $original_lump->copy();
unset( 
$other_lump->size );
echo 
"after unsetting in copy:\n";
var_dump$original_lump ); // i'm afraid so -- original value clobbered !

echo "</pre>\n";
?>

actually, it's not entirely true that php5 will only return public members....php5 will return any variable IT HAS ACCESS TO

In other words, if you do a get_class_variables($this) inside a class, you'll get everything - public, private, the whole shebang...really annoying since you can't check to see what's private/public without using reflection
2004-10-27 11:02:58
http://php5.kiev.ua/manual/ru/function.get-object-vars.html
You can still cast the object to an array to get all its members and see its visibility. Example:

<?php

class Potatoe {
    public 
$skin;
    protected 
$meat;
    private 
$roots;

    function 
__construct $s$m$r ) {
       
$this->skin $s;
       
$this->meat $m;
       
$this->roots $r;
    }
}

$Obj = new Potatoe 12);

echo 
"<pre>\n";
echo 
"Using get_object_vars:\n";

$vars get_object_vars $Obj );
print_r $vars );

echo 
"\n\nUsing array cast:\n";

$Arr = (array)$Obj;
print_r $Arr );

?>

This will returns:

Using get_object_vars:
Array
(
    [skin] => 1
)

Using array cast:
Array
(
    [skin] => 1
    [ * meat] => 2
    [ Potatoe roots] => 3
)

As you can see, you can obtain the visibility for each member from this cast. That which seems to be spaces into array keys are '\0' characters, so the general rule to parse keys seems to be:

Public members: member_name
Protected memebers: \0*\0member_name
Private members: \0Class_name\0member_name

I've wroten a obj2array function that creates entries without visibility for each key, so you can handle them into the array as it were within the object:

<?php

function obj2array ( &$Instance ) {
   
$clone = (array) $Instance;
   
$rtn = array ();
   
$rtn['___SOURCE_KEYS_'] = $clone;

    while ( list (
$key$value) = each ($clone) ) {
       
$aux explode ("\0"$key);
       
$newkey $aux[count($aux)-1];
       
$rtn[$newkey] = &$rtn['___SOURCE_KEYS_'][$key];
    }

    return 
$rtn;
}

?>

I've created also a <i>bless</i> function that works similar to Perl's bless, so you can further recast the array converting it in an object of an specific class:

<?php

function bless ( &$Instance$Class ) {
    if ( ! (
is_array ($Instance) ) ) {
        return 
NULL;
    }

   
// First get source keys if available
   
if ( isset ($Instance['___SOURCE_KEYS_'])) {
       
$Instance $Instance['___SOURCE_KEYS_'];
    }

   
// Get serialization data from array
   
$serdata serialize $Instance );

    list (
$array_params$array_elems) = explode ('{'$serdata2);
    list (
$array_tag$array_count) = explode (':'$array_params);
   
$serdata "O:".strlen ($Class).":\"$Class\":$array_count:{".$array_elems;

   
$Instance unserialize $serdata );
    return 
$Instance;
}
?>

With these ones you can do things like:

<?php

define
("SFCMS_DIR"dirname(__FILE__)."/..");
require_once (
SFCMS_DIR."/Misc/bless.php");

class 
Potatoe {
    public 
$skin;
    protected 
$meat;
    private 
$roots;

    function 
__construct $s$m$r ) {
       
$this->skin $s;
       
$this->meat $m;
       
$this->roots $r;
    }

    function 
PrintAll () {
        echo 
"skin = ".$this->skin."\n";
        echo 
"meat = ".$this->meat."\n";
        echo 
"roots = ".$this->roots."\n";
    }
}

$Obj = new Potatoe 12);

echo 
"<pre>\n";
echo 
"Using get_object_vars:\n";

$vars get_object_vars $Obj );
print_r $vars );

echo 
"\n\nUsing obj2array func:\n";

$Arr obj2array($Obj);
print_r $Arr );

echo 
"\n\nSetting all members to 0.\n";
$Arr['skin']=0;
$Arr['meat']=0;
$Arr['roots']=0;

echo 
"Converting the array into an instance of the original class.\n";
bless $ArrPotatoe );

if ( 
is_object ($Arr) ) {
    echo 
"\$Arr is now an object.\n";
    if ( 
$Arr instanceof Potatoe ) {
        echo 
"\$Arr is an instance of Potatoe class.\n";
    }
}

$Arr->PrintAll();

?>

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
In PHP5 to get an array with all properties (even the private ones) all you have to do is write a public method that returns an array for your class:

public function getArray()
{
  return get_object_vars($this);
}

and then

$myBeautifulArray = $myBeautifulObject->getArray ();

Have BEAUTIFUL day :)

If you want to access all properties (private, protected, public) of a class and his base class(es) from outside the object you can take a look in the code below.
You can even reffrence them.

Example:
<?php

// Dummy class to act as parent class.
class Dummy
{
    private       
$d1 1;
    protected   
$d2 2;
    public       
$d3 3;
}

// The class to test on.
class Test extends Dummy
{
    private       
$t1 11;
    protected   
$t2 12;
    public       
$t3 13;
}

// Instance of the test class.
$test =& new Test();

// The propertynames of the test class and his parent.
$nameD1 "\0Dummy\0d1";    // class Dummy, private      $d1
$nameD2 "\0*\0d2";        // class Dummy, protected $d2
$nameD3 "d3";            // class Dummy, public    $d3

$nameT1 "\0Test\0t1";        // class Test,  private      $t1
$nameT2 "\0*\0t2";        // class Test,  protected $t2
$nameT3 "t3";            // class Test,  public    $t3

// Printing all members (private, protected, public) of test class and parent.
// These are the values at construction.
print("Original object:\n");

Subject: using "sql_calc_found_rows" in a MySQL query while exploiting result in a PHP db class object.

Hello,

There is a nice function in MySQL that allows to know how many records would have been returned if no "where" clause were set : SQL_CALC_FOUND_ROWS.

If you have create a db object to collect the returned lines, you will be a little perplex when trying to call the result of this function.

Why ?
Simply because the returned field's name is "found_rows()" and obviously it's not possible to call something like :

<?php $result->found_rows() ?>

...as it will try to acces a method, not a property !

Then, the only way to get the right result seems to be the use of a class function, like :

<?php
  $db
->query("select found_rows()");
 
$count=current(get_object_vars(current($db->result)));
?>

Of course, if somebody found an other way to solve it, like a special syntax (see the one used with curled arrays in a string), I'm really open to discuss.

Good luck,
Pascal

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
Since there's no apparent means of obtaining all the *private* properties in an object I wrote a little function to do it.  Built in support would be much more efficient since mine uses a preg_  search to do this....

<?php

function get_private_properties($obj$inside=false)
{
   
$obj_dump  print_r($obj1);
   
preg_match_all('/^\s+\[(\w+):private\]/m'$obj_dump$matches);
    if (
$inside)
    {
       
$output = array();
        foreach (
$matches[1] as $property)
        {
           
$output[$property] = $obj->$property;
            return 
$output;
        }
    }
    else return 
$matches[1];


?>

So if you run it with the optional second paramter missing you'll just get an array of the variable names that are private inside the class.  This is the only option if you are not inside the actual object and the object has no private properties inherited.

If you run it with the second parameter set to true you will get an associative array with the properties and their corresponding values.  I'd only advise to do that for singletons since you may get errors if there are any private properites in parents/children.

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
Note that get_object_vars() returns the variables of the object not the class. You need to know if your class is extended from a parent class.

Hi all, I just wrote a function which dumps all the object propreties and its associations recursively into an array. Here it is..

function object_to_array($obj) {
       
$_arr is_object($obj) ? get_object_vars($obj) : $obj;
        foreach (
$_arr as $key => $val) {
               
$val = (is_array($val) || is_object($val)) ? object_to_array($val) : $val;
               
$arr[$key] = $val;
        }
        return 
$arr;
}
?>

Example:
You have an object like this:
fruitsbasket Object
(
    [Fruits] => Array
        (
            [0] => fruits Object
                (
                    [_name] => Mango
                    [_color] => Green
                    [_weight] => 10
                )

            [1] => fruits Object
                (
                    [_name] => Apple
                    [_color] => Red
                    [_weight] => 15
                )

            [2] => fruits Object
                (
                    [_name] => Grape
                    [_color] => Purple
                    [_weight] => 5
                )

        )

    [total_weight] => 30
)

just do:
<?php
$the_array 
object_to_array($the_object);
print_r($the_array);
?>

it will produce an array:
Array
(
    [Fruits] => Array
        (
            [0] => Array
                (
                    [_name] => Mango
                    [_color] => Green
                    [_weight] => 10
                )

            [1] => Array
                (
                    [_name] => Apple
                    [_color] => Red
                    [_weight] => 15
                )

            [2] => Array
                (
                    [_name] => Grape
                    [_color] => Purple
                    [_weight] => 5
                )

        )

    [total_weight] => 30
)

I wish function like this could be usefull for you all. :)

To follow the code of d11wtq (enquiries AT chriscorbyn.co.uk). I did this function to inspect all properties(public, private, protected) of object. 

<?php
header
("content-type: text/plain");

// Classes to test!
class OtherClass
{
    private 
$privateVarOtherClass 11;
}

class 
MyClass extends OtherClass
{
    protected 
$protectedVar "some";
    public 
$publicVar "nk";
    private 
$privateVar "algo";
    var 
$oldStyle;
}

// Dangerous function
function get_properties($obj$values=false)
{
   
$obj_dump  print_r($obj1);
   
$matches =  array();
   
preg_match_all('/^\s+\[(\w+).*\] => (\w*)/m'$obj_dump$matches);
    if (
$values)
    {
       
$output = array();
        foreach (
$matches[1] as $key => $property)
        {
           
$output[$property] = $matches[2][$key];
        }
        return 
$output;
    }
    else
    {
        return 
$matches[1];
    }
}

$instance = new MyClass();

echo 
"Properties\n";
print_r(get_properties($instance));

echo 
"Properties and values\n";
print_r(get_properties($instancetrue));

?>

Note: remember that static properties are not visible to the object. By that not supported to them

Very simple function to convert any Subobject to an array.
Created it while working with Soap.
For me as an beginner with PHP, very useful :o)

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
This is a slight modification of the previous poster's function.  We ran into a problem using this function when we had a JS array nested inside a JS hash.

Something like this...

myHash = new Hash();
myHash[address] = new Array();

When we threw that at this function, it found the first hash as an object, and then using the previous poster's function, it did not consider the array as an "object."  Instead it gave us a std_object type and we were unable to make any use of it.

The modification we made was adding a check for is_array inside both the is_object and is_array checks when you call the function.  This checks for an array inside either an object or a nested array.

function conv_obj($Data){
    if(is_object($Data)){
   
        foreach(get_object_vars($Data) as $key=>$val){
            if(is_object($val) || is_array($val)){
                $ret[$key]=conv_obj($val);
            }else{
                $ret[$key]=$val;
            }
        }
        return $ret;
    }elseif(is_array($Data)){
        foreach($Data as $key=>$val){
            if(is_object($val) || is_array($val)){
                $ret[$key]=conv_obj($val);
            }else{
                $ret[$key]=$val;
            }
        }
        return $ret;
    }else{
        return $Data;
    }

Just thought I would pass this on.

Working with PHP 5.2.4

In Windows this works by reading the vars from the passed in object and copying them to the vars of the current object.

    public function copyMe(User $user) {
        $varArray = get_object_vars($this);
        $copyVarArray = get_object_vars($user);
        foreach ($varArray as $key=>$value) {
            $this->$key = $copyVarArray[$key];
        }
    }

This did not work in Linux, I had to add another function to return the array of vars. Calling get_array_vars on the passed in object would return an empty array.

        public function copyMe(User $user) {
        $varArray = $this->getArray();
        $copyVarArray = $user->getArray();
        foreach ($varArray as $key=>$value) {
            $this->$key = $copyVarArray[$key];
        }
    }

    public function getArray() {
        return get_object_vars($this);
    }

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
get_object_vars() has confusing behaviour when called as get_object_vars($this) or similar: since a method inside a class definition can access private vars, apparently so can get_object_vars(), so it returns private vars as well. 

A simple workaround is to define a method that in itself calls get_object_vars, like:

<?php
function getPublicObjectVars($obj) {
  return 
get_object_vars($obj);
}

class 
Smth {
  private 
$notShown 1;
  public 
$shown 2;

  function 
test() {
   
$vars get_object_vars($this); // includes 'notShown'
   
$vars getPublicObjectVars($this); // only 'shown'
 
}

}
?>

http://php5.kiev.ua/manual/ru/function.get-object-vars.html
If you're using the SPL ArrayObject class (or similar, or the ArrayAccess interface), you may have noticed that it's difficult to loop through an object's properties. 

get_object_vars does not return the properties of an ArrayObject.  The only workaround I can see is to use get_class_vars.

<?php
$obj 
= new ArrayObject();
$obj->foo "bar";
$obj[] = "1";
$obj[] = "2";
foreach(
$obj as $key => $value) {
 
// will iterate over the array, iterating over "1" and "2", but ignoring $obj->foo
}

var_dump($obj); // dumps the array values, ignores $obj->foo

$a get_object_vars($obj); // returns an empty array

class Fart extends ArrayObject {
    public 
$foo "bar";
}

$obj = new Fart();
$a get_object_vars($obj); // return an empty array
$a get_class_vars(get_class($obj)); // returns array("foo"=>"bar"), Yay!

/* The above works with subclasses as well */
class Toot extends Fart {
    public 
$weeble "wobble";
}

$a get_class_vars(get_class($obj)); 
// returns array("weeble" => "wobble", "foo"=>"bar"), Yay again!

?>

So, to iterate over the properties of an ArrayObject, and not the array values:

<?php

$obj 
= new Toot(); // which is a subclass of ArrayObject
$props get_class_vars(get_class($obj));
foreach(
$props as $prop => $defaultValue) {
 
$value $obj->$prop// now you have the property name and  its value
}

?>

Be aware of the fact that this is scope-sensitive. If you're calling this from an objects own method, then private and protected vars will be outputted as well. Call it from outside the object and the result will most likely be what you want to archive.
2009-12-26 15:31:49
http://php5.kiev.ua/manual/ru/function.get-object-vars.html
Also note that this is recursive. For example:

<?php
class Sarah{

    private 
$Father;
    private 
$Mother;

    public function 
__construct(){
       
$this->Father    =    NULL//I don't know Sarah's Father
       
$this->Mother    =    NULL//I don't know Sarah's Mother
   
}
}
class 
John_Connor{

    private 
$Father;
    private 
$Mother;

    public function 
__construct(){
       
$this->Father    =    $this//John went back in time and fathered himself
       
$this->Mother    =    new Sarah(); //Sarah was his mom and his mate ewww
   
}

    public function 
showParents(){
        return 
get_object_vars($this);
    }
}

$John    =    new John_Connor();
var_dump($John->showParents());
?>

You will see this outputs:

array(2) {
  ["Father"]=>
  object(John_Connor)#1 (2) {
    ["Father":"John_Connor":private]=>
    object(John_Connor)#1 (2) {
      ["Father":"John_Connor":private]=>
      *RECURSION*
      ["Mother":"John_Connor":private]=>
      object(Sarah)#2 (2) {
        ["Father":"Sarah":private]=>
        NULL
        ["Mother":"Sarah":private]=>
        NULL
      }
    }
    ["Mother":"John_Connor":private]=>
    object(Sarah)#2 (2) {
      ["Father":"Sarah":private]=>
      NULL
      ["Mother":"Sarah":private]=>
      NULL
    }
  }
  ["Mother"]=>
  object(Sarah)#2 (2) {
    ["Father":"Sarah":private]=>
    NULL
    ["Mother":"Sarah":private]=>
    NULL
  }
}

It seems like there's no function that determines all the *static* variables of a class.

I've come out with this one as I needed it in a project:

<?php
function get_class_static_vars($object) {
     return 
array_diff(get_class_vars(get_class($object)), get_object_vars($object));
}
?>

It relies on an interesting property: the fact that get_object_vars only returns the non-static variables of an object.

A simple way to call this function within an Object and to only export the *public* params would be to artificially change the scope - for example with a closure in php 5.3:

<?php
class Example
{
    public 
$publicSetting 'public';
    protected 
$protectedSetting 'protected';
    private 
$privateSetting 'private';
   
    public function 
showEverything()
    {
        return 
get_object_vars($this);
    }
   
    public function 
showMyPublicsOnly()
    {
       
$me $this;
       
$publics = function() use ($me) {
            return 
get_object_vars($me);
        };
        return 
$publics();
    }
}

You can use call_user_func() to return public variables from inside the class:

class Test {
    protected $protected;
    public $public;
    private $private;

    public function getPublicVars () {
        return call_user_func('get_object_vars', $this);

}

$test = new Test();
var_dump($test->getPublicVars()); // array("public" => NULL)

I find this function very helpful, What i wanted to do was to get the object properties of an exception so i could sanitize them for output.

       
   try
   {
       throw new Exception( 'Test Exception.', 100 );
   }
   catch( Exception $e )
   {
       var_dump( ( object ) get_object_vars( ( object ) ( new ArrayObject( $e ) ) -> getarrayCopy() ) );
   }

Example return:

object(stdClass)#10 (4) { ["message"]=> string(15) "Test Exception." ["code"]=> int(100) ["file"]=> string(29) "C:\xampp\htdocs\dev\index.php" ["line"]=> int(19) }

If your object contains a reference, beware that you might get references for all object properties in the array values, thus when changing values in the array, they may change the object too (confirmed and not yet fixed PHP bug https://bugs.php.net/bug.php?id=66961 affecting all PHP versions up to at least 5.6.2 and 5.5.18 and 5.4.34).

This 10-years old comment tried reporting this: function.get-object-vars#40515 but its exemple was incomplete. See bug report for example.
