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');
?>

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
?>

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

In order to get class attributes look here (php8)

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"
}
}
