php: static call on non-static function
Somebody asked on the php Google Group on how to make a static call on a non-static function. (don’t ask me why) Here is my (very nasty) solution :
<?php
abstract class SomeClass
{
protected function test() {
echo "test 42";
}
}
class AnotherClass extends SomeClass {
private static $_instance = null;
public static function __callStatic($name, $args) {
if(is_null($_instance)) {
self::$_instance = new __CLASS__;
}
if(method_exists(self::$_instance, $name)) {
call_user_func_array(array(self::$_instance, $name), $args);
}
}
public function test() {
parent::test();
return " 43";
}
}
echo AnotherClass::test();
//outout test 42 43
Basically, we use the magic method __callStatic, and we create a Singleton instance of our object to take care of any static call on a non-static function. Might not work for all the cases, but does the job. And again, it’s nasty.
