1.2.958. Parent Is Not Static¶
The parent keyword behaves like self, not like static. It links to the parent of the defining expression, not to the one being called.
This may skip the parent of the calling class, and create a Undefined method call, or yield the wrong ::class value. It may also skip a local version of the method.
<?php
class w {
}
class x extends w {
function foo() {
parent::method();
}
// method() is in the parent of Y, but not in the one of X.
function method() {
print __METHOD__;
}
}
class y extends x {}
(new y)->foo();
// print W::method
(new y)->method();
// print x::method
?>
