Help with <?=$_SERVER['PHP_SELF']?>

[neobie]

as we know <?=$SERVER['PHP_SELF']?> will let the php load the same page, let say index.php itself.
anyway if my current url is 'index.php?sort=3' how can i load the page itself since the <?=$SERVER['PHP_SELF']?> will only load 'index.php' without '?sort=3' .
Thanks for any helps.

use $SERVER['PHP_SELF'] in conjunction with $SERVER['QUERY_STRING']

or $_SERVER['REQUEST_URI'] if available

<form action="<?=$_SERVER['PHP_SELF']?>?sort=3">

This isn't very practical as you - typically - won't know what sort equals.

<?php
$self=$_SERVER['PHP_SELF'];
$sort=$_GET['sort'];
?>

<form action="<?=$self?>?sort=<?=$sort?>">

This is how I would do it.

and yours isn't very practical if you don't know about or care about any of the specific GET vars that were passed (see my suggestion above).

Thanks, $SERVER['QUERY_STRING'] does solve my problem. my index.php contain a table with sorting function, if the user doesnt sort the table $SERVER['QUERY_STRING'] is very useful in checking whether there is query_string (?sort=)
