class_parents — Return the parent classes of the given class
This function returns an array with the name of the parent classes of
the given object_or_class.

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));
?>The above example will output something similar to:
Array
(
[foo] => foo
)
Array
(
[foo] => foo
)
Array
(
[parent_of_not_loaded] => parent_of_not_loaded
)
Note: To check that an object extends a class,
instanceofor the is_a() function should be used instead.
instanceof<?php
class foo {}
class bar extends foo {}
class baz extends bar {}
print_r(class_parents(new baz));
?>
Will output:
Array
(
[bar] => bar
[foo] => foo
)
