照片圖庫

include("include/common.inc");
$title = "Gallery";
include("include/header.inc");

Here are some of our family photos. This PHP script can really
be made better, by splitting into multiple pages.

$d = dir("photos");
while($entry = $d->read())
{
if (is_file("photos/$entry"))
echo "n";
}
$d->close();
?>
include("include/footer.inc");
?>

　　 另外，你可以在文件上傳的表單中加上一個輸入元素去描述該上傳的文件。這個元素將被存儲在文件中，然后被以上的照片圖庫的那段代碼所讀出并顯示出來。
