php 页面参数过多时自动拼接get参数的函数

function getUri($query){   
            $request_uri = $_SERVER["REQUEST_URI"];
            $url = strstr($request_uri,'?') ? $request_uri :  $request_uri.'?';
             
            if(is_array($query))
                $url .= http_build_query($query);
            else if($query != "")
                $url .= "&".trim($query, "?&");
         
            $arr = parse_url($url);
 
            if(isset($arr["query"])){
                parse_str($arr["query"], $arrs);
                unset($arrs["page"]);
                $url = $arr["path"].'?'.http_build_query($arrs);
            }
             
            if(strstr($url, '?')) {
                if(substr($url, -1)!='?')
                    $url = $url.'&';
            }else{
                $url = $url.'?';
            }

function auto_get($except=array()){
    $p_url=$_SERVER['QUERY_STRING'];
