Examples
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
)
