 @$type = $_FILES['file']['type'];
 @$size = $_FILES['file']['size'];
 
 @$extension = substr($name, (strpos($name, '.'))+1);

 @$tmp_name = $_FILES['file']['tmp_name'];

 if(@isset($name) && @!empty($name)){

  if($extension == 'jpg' || $extension == 'jpeg'){

 $location = 'tnw87/';
    if(move_uploaded_file($tmp_name, $location.$name)) {
      echo $name.' is successfully uploaded!';
    } else{
      echo 'Upload Errors';
    }
    }else{
      echo 'Your file type is <strong>'.$extension. ' !</strong></br>';
      echo 'Only <b>jpg</b> or <b>jpeg</b> is allowed to upload!';
