Description

mixed call_user_func ( callback function [, mixed parameter [, mixed ...]])

Call a user defined function given by the function parameter. Take the following:


<?php
function barber($type) 
{
    echo "You wanted a $type haircut, no problem";
}
call_user_func('barber', "mushroom");
call_user_func('barber', "shave");
?>

Object methods may also be invoked statically using this function by passing array($objectname, $methodname) to the function parameter.


<?php
class myclass {
  function say_hello() 
  {
    echo "Hello!\n";
  }
}

$classname = "myclass";

call_user_func(array($classname, 'say_hello'));
?>
