Note to users: language constructs (eval, die, exit, isset, unset, echo etc.) which might be confused with functions, cannot be renamed or redefined even with runkit.internal_override.

Here is another example with a parameter:



<?php



function hello_world($word) {

  echo "Original Hello World: $word\n</br>";

}



$helloWorld = 'echo "Redefined Hello World: $word\n</br>";';



hello_world('test1');



runkit_function_redefine('hello_world', '$word', $helloWorld);



hello_world('test2');



?>
