Example #1 class_implements() example
<?php
interface?foo?{?}
class?bar?implements?foo?{}
print_r(class_implements(new?bar));
//?since?PHP?5.1.0?you?may?also?specify?the?parameter?as?a?string
print_r(class_implements('bar'));
function?__autoload($class_name)?{
???require_once?$class_name?.?'.php';
}
//?use?__autoload?to?load?the?'not_loaded'?class
print_r(class_implements('not_loaded',?true));
?>
The above example will output something similar to:
Array
(
[foo] => foo
)
Array
(
[interface_of_not_loaded] => interface_of_not_loaded
)
