Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

Parameters

classname: The class in which to redefine the method

code: The new code to be evaluated when methodname is called
flags: The redefined method can be CLASSKIT_ACC_PUBLIC, CLASSKIT_ACC_PROTECTED or CLASSKIT_ACC_PRIVATE

Examples

Example 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
);
