$file = $_FILES["upfile"];
if($max_file_size < $file["size"])
//检查文件大小
{
echo "文件太大！";
exit;
}

if(!in_array($file["type"], $uptypes))
//检查文件类型
{
echo "只能上传图像文件或Flash！";
exit;

不知道这个算不算一句
call_user_func( function($size){ list($width,$height) = $size; return $width>500 and $height>500; }, getimagesize('a.png')));
