代码：

/*** @desc：获取前端提交的数据，支持数据过滤* @author [Lee] <[<complet@163.com>]>*/class getrequest{/* @desc：内部函数：过滤危险数据 */private function safetydata($data){ foreach($data as $k=>$v){ if(is_array($v)){ $data[$k] = $this->safetydata($v); }else{ $tmp = trim($v); $tmp = addslashes($tmp); $data[$k] = $tmp; } } return $data;}/* @desc：判断前端传入方式，转换成能用数据 */public function getrequestdata(){ $data; $ret; $contenttype = strtolower($_SERVER['CONTENT_TYPE']); $method = strtolower($_SERVER['REQUEST_METHOD']); if($contenttype == 'application/json'){ $data = file_get_contents('php://input'); $data = json_decode($data,true); }elseif(in_array($contenttype,array('application/x-www-form-urlencoded','multipart/form-data')) || $method == 'post'){ $data = $_POST; }elseif(in_array($contenttype,array('application/x-www-form-urlencoded','multipart/form-data')) || $method == 'get'){ $data = $_GET; }else{ parse_str(file_get_contents('php://input'),$data); } $ret = $this->safetydata($data); return $ret;}}用法：

$getrequest = new getrequest();$data = $getrequest->getrequestdata();var_dump($data);测试
