runkit_function_redefine

(PECL runkit >= 0.7.0)

Replace a function definition with a new implementation

bool runkit_function_redefine ( string $funcname, string $arglist, string $code )

Note: By default, only userspace functions may be removed, renamed, or modified. In order to override internal functions, you must enable the runkit.internal_override setting in php.ini.

Parameters:

funcname

Name of function to redefine

arglist

New list of arguments to be accepted by function

code

New code implementation

Returns:

Returns TRUE on success or FALSE on failure.

Examples:

A runkit_function_redefine() example

<?php
function testme() {
  echo "Original Testme Implementation\n";
}
testme();
runkit_function_redefine('testme','','echo "New Testme Implementation\n";');
testme();
?>

The above example will output:

Original Testme Implementation
New Testme Implementation
