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

`methodname`

  The name of the method to redefine

`args`

  Comma-delimited list of arguments for the redefined method

`code`

  The new code to be evaluated when `methodname` is called

`flags`

  The redefined method can be `RUNKIT_ACC_PUBLIC`, `RUNKIT_ACC_PROTECTED` or `RUNKIT_ACC_PRIVATE`

### Examples

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:

    Before: foo!
    After: bar!
