Коментарии
To reflect on a namespaced class in PHP 5.3, you must always specify the fully qualified name of the class - even if you've aliased the containing namespace using a "use" statement.
So instead of:
<?php
use App\Core as Core;
$oReflectionClass = new ReflectionClass('Core\Singleton');
?>
You would type:
<?php
use App\Core as Core;
$oReflectionClass = new ReflectionClass('App\Core\Singleton');
?>
Unserialized reflection class cause error.
<?php
/**
* abc
*/
class a{}
$ref = new ReflectionClass('a');
$ref = unserialize(serialize($ref));
var_dump($ref);
var_dump($ref->getDocComment());
// object(ReflectionClass)#2 (1) {
// ["name"]=>
// string(1) "a"
// }
// PHP Fatal error: ReflectionClass::getDocComment(): Internal error: Failed to retrieve the reflection object
?>
Reflecting an alias will give you a reflection of the resolved class.
<?php
class X {
}
class_alias('X','Y');
class_alias('Y','Z');
$z = new ReflectionClass('Z');
echo $z->getName(); // X
?>
It is also possible to do reflection from within the class and get the methods for instance.
<?php
class test
{
private $test = "";
public function setTest($test)
{
$this->test = $test;
return $this;
}
public function getTest()
{
return $this->test;
}
public function run(){
$class = new ReflectionClass('test');
$methods = $class->getMethods();
var_dump($methods);
}
}
Called from another php file you get the proper result:
array(3) {
[0]=>
&object(ReflectionMethod)#3 (2) {
["name"]=>
string(8) "setTest"
["class"]=>
string(4) "test"
}
[1]=>
&object(ReflectionMethod)#4 (2) {
["name"]=>
string(8) "getTest"
["class"]=>
string(4) "test"
}
[2]=>
&object(ReflectionMethod)#5 (2) {
["name"]=>
string(3) "run"
["class"]=>
string(4) "test"
}
}
