Note Submitter: rsalazar@universia.net.mx ---- Yet another version of this function. I've been using this one and seems to work just fine. It adds (if it doesn't exist) or replaces (if it exists) the $value of the $param on the $query :) If $ceol (cleanEndOfLine) is evaluated as TRUE and the $param is found, anything after that will be deleted —don't ask, it was useful... once <?php function replaceOnQueryString( $query, $param, $value = NULL, $ceol = FALSE ) if( !is_null($value) && !preg_match('/(^|\?|&)'. $param .'=/i', $query) ) return $query .($query ? '&' : ''). $param .'='. $value; $pattern = '/(^|\?|&)('. $param .((bool)$ceol ? ')=.*$/i' : ')(=[^&]*)?/i'); return preg_replace($pattern, is_null($value) ? '' : '$1$2='. $value, $query); } ?> I'm not sure if I'm keeping it simple or making difficult what already is simple, but here you have anyway
