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

?>

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');
?>
