Syntax of class_parents
array class_parents(mixed class[, bool autoload_class])
If class is an object, returns an array containing the names of the parents of class’s object class. If class is a string, returns an array containing the class names of the parents of the class named class. Returns false if class is neither an object nor a string, or if class is a string but no object class of that name exists. If autoload_class is set and is true, the class is loaded through the class’s __autoload() function before getting its parents.
Example of class_parents
<?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));
?>
Array
(
[foo] => foo
)
Array
(
[foo] => foo
)
Array
(
[parent_of_not_loaded] => parent_of_not_loaded
)
