php如何解析url中的中文字符

function urlConvert($url){   
        $pathArr = array();   
        $modules = parse_url($url);   
        $path = $modules['path'];   
        $pathSplit = explode(‘/', $path);   
       
        foreach ($pathSplit as $row){   
            $pathArr[] = rawurlencode($row);   
        }   
        $urlNew = $modules['scheme']."://".$modules['host'].implode(‘/', $pathArr);   
        return $urlNew;   
    }
