ReflectionProperty::getValue

(PHP 5)

ReflectionProperty::getValueGets value

Description

public mixed ReflectionProperty::getValue ([ object $object ] )

Gets the properties value.

Parameters

object

If the property is non-static an object must be provided to fetch the property from. If you want to fetch the default property without providing an object use ReflectionClass::getDefaultProperties() instead.

Return Values

The current value of the property.

Errors/Exceptions

Throws a ReflectionException if the property is inaccessible. You can make a protected or private property accessible using ReflectionProperty::setAccessible().

Examples

Example #1 ReflectionProperty::getValue() example

<?php
class Foo {
    public static 
$staticProperty 'foobar';
    
    public 
$property 'barfoo';
    protected 
$privateProperty 'foofoo';
}

$reflectionClass = new ReflectionClass('Foo');

var_dump($reflectionClass->getProperty('staticProperty')->getValue());
var_dump($reflectionClass->getProperty('property')->getValue(new Foo));

$reflectionProperty $reflectionClass->getProperty('privateProperty');
$reflectionProperty->setAccessible(true);
var_dump($reflectionProperty->getValue(new Foo));
?>

The above example will output:

string(6) "foobar"
string(6) "barfoo"
string(6) "foofoo"

To allow protected and private properties to be accessed, you should use
ReflectionProperty::setAccessible(bool $accessible):

<?php
/** Class Foo with protected and private members */
class Foo {
    protected 
$bar 'barrr!';
    private 
$baz 'bazzz!';
}

$reflFoo = new ReflectionClass('Foo');
$reflBar $reflFoo->getProperty('bar');
$reflBaz $reflFoo->getProperty('baz');

// Set private and protected members accessible for getValue/setValue
$reflBar->setAccessible(true);
$reflBaz->setAccessible(true);

$foo = new Foo();
echo 
$reflBar->getValue($foo); // will output "barrr!"
echo $reflBaz->getValue($foo); // will output "bazzz!"

// You can also setValue
$reflBar->setValue($foo"new value");
echo 
$reflBar->getValue($foo); // will output "new value"
?>
