>我正在上传照片,像你说的那样移动照片：

$image = md5_file($_FILES['image']['tmp_name']);
// you can add a random number to the file name just to make sure your images will be "unique"
$image = md5(mt_rand().$image);
$folder = $image[0]."/".$image[1]."/".$image[2]."/";

// IMAGES_PATH is a constant @R_304_1413@d in my global config
define('IMAGES_PATH','/path/to/my/images/');
// coolparty = f3d40fc20a86e4bf8ab717a6166a02d4
$folder = IMAGES_PATH.$folder.'f3d40fc20a86e4bf8ab717a6166a02d4.jpg';
// thumbnail,I just apPEnd the t_ before image name
$folder = IMAGES_PATH.$folder.'t_f3d40fc20a86e4bf8ab717a6166a02d4.jpg';
// move_uploaded_file(),wITh thumbnail after PRocess
// also make sure you create the folders in mkdir() before you move them

>我确实相信是基本的方式,当然你可以将文件夹结构更改为更深的一个,就像你说的那样,如果你有数百万张图片,可以使用2个字符.
