php接收客户端上传图片用POST来传输图片流

//base64二进制图片流$file_name = base64_decode($_POST['images']);//验证头像格式$bin = substr($file_name,0,2);  $strInfo = @unpack("C2chars", $bin);  $typeCode = intval($strInfo['chars1'].$strInfo['chars2']);  $fileType = '';  switch ($typeCode)  {      case 7790:          $fileType = 'exe';          break;      case 7784:          $fileType = 'midi';          break;      case 8297:          $fileType = 'rar';          break;      case 255216:          $fileType = 'jpg';          break;      case 7173:          $fileType = 'gif';          break;      case 6677:          $fileType = 'bmp';          break;      case 13780:          $fileType = 'png';          break;      default:          echo 'unknown';  }     if(!empty($file_name)||!empty($user_id)){    $upfile='images/face/'.'face_'.'123'.'.jpg';    $file=$_SERVER['DOCUMENT_ROOT'].'/images/face/'.'face_'.'123'.'.jpg';    $m=fopen($file,"w");//当参数为"w"时是将内容覆盖写入文件，而当参数为"a"时是将内容追加写入。    //$content=$result['keyword']."\t\t\n";    fwrite($m,$file_name);    fclose($m);        json(200,'success',1);    }else{        json(401,'error',0);        }
