    Functions are nothing more than reusable chunks of code that accept variable input and provide variable output. Functions are synonymous to other languages which may refer to them as subroutines, or in object oriented languages they are methods. PHP supports no ability to overload its function nor methods.
    PHP Code:
    header('HTTP/1.1 420 Enhance Your Calm');

    That is no way near all the functions for php. The best php manual is the official one at www.php.net

    As Fou says..: http://www.php.net/manual/en/funcref.php

    The w3 schools are IMO useless. Sure, they're a very gentle break-me-in way of learning but they are not a solid way of learning php at all.
    See my new CodingForums Blog: http://www.codingforums.com/blogs/tangoforce/

    Many useful explanations and tips including: Cannot modify headers - already sent, The IE if (isset($_POST['submit'])) bug explained, unexpected T_CONSTANT_ENCAPSED_STRING, debugging tips and much more!
