Is it possible to check whether or not a method has been overridden by a child class in PHP?
<!-- language: lang-php -->
class foo {
protected $url;
protected $name;
protected $id;
var $baz;
function __construct($name, $id, $url) {
$this->name = $name;
$this->id = $id;
$this->url = $url;
}
function createTable($data) {
// do default actions
}
}
Child class:
class bar extends foo {
public $goo;
public function createTable($data) {
// different code here
}
}
When iterating through an array of objects defined as members of this class, how can I check which of the objects has the new method as opposed to the old one? Does a function such as method_overridden(mixed $object, string $method name)
exist?
foreach ($objects as $ob) {
if (method_overridden($ob, "createTable")) {
// stuff that should only happen if this method is overridden
}
$ob->createTable($dataset);
}
I am aware of the template method pattern, but let's say I want the control of the program to be separate from the class and the methods themselves. I would need a function such as method_overridden
to accomplish this.
