I can't for the life of me figure out why my attempts at using $_GET are not working. As near as I can tell, I'm using it correctly, as I've used it in the past.

The link seems to be formatted correctly

<a href="script.php?variable=value">Value</a>

since I receive the correct information in the URL:

localhost.com/script.php?variable=value

but neither simply using:

$var = $_GET['variable'];

or using either of these two:

if (!isset($_GET['variable'])) { $var = $_GET['variable']; } if (isset($_GET['variable'])) { $var = $_GET['variable']; }

nothing I do seems to be working, does anyone have any suggestions as to what to look out for?

    It's possible that the request is being rewritten by something like .htaccess (without the [QSA] flag). You can also check out the value of the php.net/manual/en/ini.core.php#ini.variables-order setting, which can disable certain superglobals. Commented Apr 29, 2013 at 21:06

    Sounds to me like .htaccess could be rewriting it. Or, by any chance, are you using php shorthand tags (<? instead of <?php) with the short_open_tag disabled? Commented Apr 29, 2013 at 21:51
