If 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.
Example #1 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 informationvar_dump(new My_Reflection_Method('U', 'x'));?>The above example will output something similar to:
object(My_Reflection_Method)#1 (3) {
["visibility"]=>
array(1) {
[0]=>
string(6) "public"
}
["name"]=>
string(1) "x"
["class"]=>
string(1) "U"
}
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
