runkit7_method_redefine — Dynamically changes the code of the given method

### Description

runkit7_method_redefine ( string `$classname` , string `$methodname` , string `$args` , string `$code` [, int `$flags` = RUNKIT7_ACC_PUBLIC [, string `$doc_comment` = `NULL` [, string `$return_type` [, bool `$is_strict` ]]]] ) : bool
runkit7_method_redefine ( string `$classname` , string `$methodname` , Closure `$closure` [, int `$flags` = RUNKIT7_ACC_PUBLIC [, string `$doc_comment` = `NULL` [, string `$return_type` [, bool `$is_strict` ]]]] ) : bool

### 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

`closure`

  A closure that defines the method.

`flags`

  The redefined method can be `RUNKIT7_ACC_PUBLIC`, `RUNKIT7_ACC_PROTECTED` or `RUNKIT7_ACC_PRIVATE` optionally combined via bitwise OR with `RUNKIT7_ACC_STATIC`

`doc_comment`

  The doc comment of the method.

`return_type`

  The return type of the method.

`is_strict`

  Whether the method behaves as if it was declared in a file with strict_types=1.

### Return Values

Returns `TRUE` on success or `FALSE` on failure.

### Examples

Example #1 runkit7_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
runkit7_method_redefine(
'Example',
'foo',
'',
'return "bar!\n";',
RUNKIT7_ACC_PUBLIC
);
// output Example::foo() (after redefine)
echo "After: " . $e->foo();
?>`

The above example will output:

    Before: foo!
    After: bar!
