    What you specify aren't actually functions, but predefined variables. $_GET['field-name'] is an example of a get variable which is declared in the URI (for example -

    There are many predefined variables, including $_FILES, $_SERVER, $_COOKIE, $_SESSION etc

    The names relate to what they contain, for example

    $_SERVER['PHP_SELF'] is the predefined variable for the current page, $_SERVER['REMOTE_ADDR'] is the user ip address and so on.

    For all the details see the documentation on

    You can get the PHP manual downloaded from

    You can also try using

    1. ActiveState Komodo or

    2. Zend Studio

    They provide good description about the function while you type.

    Go to Google and search for "php reference" and "php tutorials". You should gain plenty of knowledge there.
