PHP实例关于FTP疑问，图片上传到图片服务器上都有哪些方法？-it技术论坛-it论坛-计算机论坛我用过的方法，供参考：
1.在iframe里面用另一表单上传图片，表单地址是图片服务器；
2.同样是上传图片后首先是存放在运行程序的服务器的临时目录里，服务器有一个对图片进行压缩、缩放等处理的shell脚本进程，这个脚本的处理完图片后，通过rsync将处理好的图片推送到图片服。
可以采用程序去处理，参考一下CI的一个类库(Ftp.php),源代码如下：
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
