Przykład #1 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));
?>

Powyższy przykład wyświetli coś podobnego do:

Array

    [foo] => foo
)

Array

)
