    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

    ?>
