if (is_uploaded_file($_FILES['userfile']['tmp_name']))

$PType=$_FILES['userfile']['type'];
$PSize=$_FILES['userfile']['size'];
$PicImageSize = GetImageSize($PicPath.$file_rename.".".$ext);
$PicWidth = $PicImageSize[0];
$PicHeight = $PicImageSize[1];
if($PicWidth > 120 || $PicHeight > 140 || $PSize > $MAX_FILE_SIZE )

}
elseif ($PType != "image/pjpeg")
{
echo "您上传的图片格式与要求不符";
