runkit_function_redefine

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

Parameters

funcname

Name of function to redefine

arglist

New list of arguments to be accepted by function

code

New code implementation

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example 2087. 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:
