Request variables: $_REQUEST
*Note: * Introduced in 4.1.0. There is no equivalent array in
earlier versions.
*Note: * Prior to PHP 4.3.0, $_FILES information was also included
in $_REQUEST.
An associative array consisting of the contents of $_GET, $_POST, and
$_COOKIE.
This is a 'superglobal', or automatic global, variable. This simply
means that it is available in all scopes throughout a script. You don't
need to do a *global $_REQUEST;* to access it within functions or methods.
If the register_globals
<http://us2.php.net/manual/en/ini.core.php#ini.register-globals>
directive is set, then these variables will also be made available in
the global scope of the script; i.e., separate from the $_REQUEST array.
For related information, see the security chapter titled Using Register
Globals <http://us2.php.net/manual/en/security.globals.php>. These
individual globals are not autoglobals.

hi..
quick question.. a basic link <a ref ="foo.php?a=1">blah</a> allows you to
process the vars in foo.php using $_GET, easy/basic enough. however, if i
have a form from cat.php that does a 'post' of the form information/input to
the foo.php, i'm then going to have to either change the form to do a 'get'
or else i'm going to have to do both a $_GET, and a $_POST within foo.php to
access the vars from the pages that are interfacing with foo.php.
is there an easier/cleaner/better approach??
or do i really need/wind up doing something like
if ($_GET['foo'])...
if ($_POST['apple'])...
and just have a mix of both methods within the code...
thanks
