Rebuild query string ver. 1.03

I modified some code created by Macromedia Dreamweaver into a flexible
function to rebuild the query string. The function is very useful for
pagination or passing variables from one page to another.In this
version it's possible to add more than one variable names into the
functions arguments. This names will be filtered from the new
generated query string. Just add the variable names you don't need
into a comma seperated string.

<?php
function rebuild_qs($curr_vars) {
if (!empty($_SERVER['QUERY_STRING'])) {
$parts = explode("&", $_SERVER['QUERY_STRING']);
$curr_vars = str_replace(" ", "", $curr_vars); // remove
whitespace
$c_vars = explode(",", $curr_vars);
$newParts = array();
foreach ($parts as $val) {
$val_parts = explode("=", $val);
if (!in_array($val_parts[0], $c_vars)) {
array_push($newParts, $val);
}
}
if (count($newParts) != 0) {
$qs = "&".implode("&", $newParts);
} else {
return false;
}
return $qs; // this is your new created query string
} else {
return false;
}
}
/* Example:
script.php?ident=1<?php echo rebuild_qs("ident, submit, var_one"); ?>
*/
?>
