# Extending

In case you want to create specialized versions of the built-in classes (say, for creating colorized HTML when being exported, having easy-access member variables instead of methods or having utility methods), you may go ahead and extend them.

Przykład #2 Extending the built-in classes

`<?php
/**
* My Reflection_Method class
*/
class My_Reflection_Method extends ReflectionMethod
{
public $visibility = array();
public function __construct($o, $m)
{
parent::__construct($o, $m);
$this->visibility = Reflection::getModifierNames($this->getModifiers());
}
}
/**
* Demo class #1
*
*/
class T {
protected function x() {}
}
/**
* Demo class #2
*
*/
class U extends T {
function x() {}
}
// Print out information
var_dump(new My_Reflection_Method('U', 'x'));
?>`

Powyższy przykład wyświetli coś podobnego do:

    object(My_Reflection_Method)#1 (3) {
      ["visibility"]=>
      array(1) {
        [0]=>
        string(6) "public"
      }
      ["name"]=>
      string(1) "x"
      ["class"]=>
      string(1) "U"
    }

Uwaga

If you're overwriting the constructor, remember to call the parent's constructor before any code you insert. Failing to do so will result in the following: Fatal error: Internal error: Failed to retrieve the reflection object
