Examples:

class_parents() example

<?php
 
class foo { }
class bar extends foo {}
 
print_r(class_parents(new bar));
 
// since PHP 5.1.0 you may also specify the parameter as a string
print_r(class_parents('bar'));
 
 
function __autoload($class_name) {
   require_once $class_name . '.php';
}
 
// use __autoload to load the 'not_loaded' class
print_r(class_parents('not_loaded', true));
?>

The above example will output something similar to:

Array
(
    [foo] => foo
)

Array
(
    [parent_of_not_loaded] => parent_of_not_loaded
)
