推薦：取得當(dāng)前插入數(shù)據(jù)庫(kù)中記錄的id值
在PHP中，經(jīng)常需要把插入數(shù)據(jù)庫(kù)中的id值取出來(lái)，而正好有這么一個(gè)函數(shù)：以下為引用的內(nèi)容： <?php //執(zhí)行插入數(shù)據(jù)庫(kù)的語(yǔ)句 //…… $get

中文方式顯示照片EXIF信息，顯示圖片中所略圖

這東西除了一些php論壇簡(jiǎn)單顯示三兩信息，別人的lb5000論壇上看到過(guò)顯示，asp的也有不過(guò)很久沒(méi)接觸看著暈。

不想重復(fù)勞動(dòng)，搜過(guò)google，除了asp沒(méi)找到其他開(kāi)源的顯示exif的，所以整理出來(lái)或許有用。

沒(méi)什么技術(shù)含量，基本只是漢化和資料整理的工作，以下代碼為主要部分，所有文件在壓縮包內(nèi)，可以廣泛用于相冊(cè)和論壇顯示圖片信息的插件，希望熟悉相關(guān)知識(shí)的朋友找找bug或者加以優(yōu)化。

目前應(yīng)該缺不少信息，如果單單使用應(yīng)該足夠了。

看到過(guò)別人傳過(guò)來(lái)的照片里面有縮略圖，photoshop做的，但是不知道怎么加進(jìn)去，有人知道么？

縮略圖可以顯示
