Примери

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));

?>

Примерът по-горе ще изведе нещо подобно на:

Array
(
    [foo] => foo
)

Array
(
    [interface_of_not_loaded] => interface_of_not_loaded
)
