Example #1 runkit_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 runkit_method_redefine( 'Example', 'foo', '', 'return "bar!\n";', RUNKIT_ACC_PUBLIC ); // output Example::foo() (after redefine) echo "After: " . $e->foo(); ?>
The above example will output:
