That is the reason why I want to use regular expression to replace : the variable & value from the string. $qstring = preg_replace('/&?page=\d*/i', '', $querystring); : Now I am using this option to remove the variable name only, so that it : will not collide with the variable value that is submitted again. Instead of using regexps on the URL, it might be easier (and safer) to loop through $_GET, build a new $geturl array, add/delete/change any variables in $geturl, then build a new $geturlstr string that can then be appended to your hyperlinks.
