照片圖庫(kù)

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";

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