Example #1 class_parents() example

<?php

class foo { }
class bar extends foo {}

print_r(class_parents(new bar));

// you may also specify the parameter as a string
print_r(class_parents('bar'));

spl_autoload_register();

// use autoloading to load the 'not_loaded' class
print_r(class_parents('not_loaded', true));

?>

Il precedente esempio visualizzerà qualcosa simile a:

)

    [foo] => foo
)

    [parent_of_not_loaded] => parent_of_not_loaded
)

class_implements() - Return the interfaces which are implemented by the given class or interface
is_a() - Verifica se l'oggetto è di questa classe o ha questa classe come una dei suoi genitori

<?php
class foo {}
class bar extends foo {}
class baz extends bar {}

print_r(class_parents(new baz));
?>

Will output:
Array
(
    [bar] => bar
    [foo] => foo
)
