PHP input data Uniform class instance, PHP Unified class instance

This article describes the PHP input data unification class. Share to everyone for your reference. Specific as follows:

<?phpclass cls_request{private $getdata;//Store get Data private $postdata;//store post data private $requestdata;// Store data for request private $filedata;//Store file data private $cookiedata;//store Cooki static $_instance;//instance of this class private function __ Construct () {$this->getdata = Self::format_data ($_get), $this->postdata = Self::format_data ($_post); $this RequestData = Array_merge ($this->getdata, $this->postdata); $this->cookiedata = Self::format_data ($_cookie); $this->filedata = Self::format_data ($_files); }//class initialization, return Cls_request object public static function Get_instance () {if (!)
