Call a user defined function with optional parameters

function_name: String containing the name of the user function to call

parameters: Optional parameters to pass to the function

Any type depending on the way the function is defined

<? 
function my_add($x,$y) {
  return $x+$y;
}
$result=call_user_func("my_add",1,3);
print($result); //output will be '4'
?>

function - Define a function

return - Return program control to the calling module

User defined functions can take many different forms, and it is not necessary to use call_user_func() to execute a function unless a direct return value is needed.

If used within a function, the return statement immediately ends execution of the function, and returns its argument as the value of the function call.
