## 範例

範例 1. classkit_method_redefine() example

`<?php class Example { function foo() { return "foo!\n"; } } // create an Example object $e = new Example(); // output Example::foo() (before redefine) echo "Before: " . $e->foo(); // Redefine the 'foo' method classkit_method_redefine( 'Example', 'foo', '', 'return "bar!\n";', CLASSKIT_ACC_PUBLIC ); // output Example::foo() (after redefine) echo "After: " . $e->foo(); ?>`
