新手求问两个问题
刚刚接触curl有几个问题想问下- -
1.php自带的上传文件($_FILES)和ftp上传文件和curl上传文件有什么区别
2.curl模拟登陆是什么意思，网上查了很多说什么模拟post、get提交但看不大懂，为什么要模拟？一般什么地方用的到？麻烦帮我通俗点说明下- -
回复讨论(解决方案)
$_FILES 中保存有上传文件的相关信息
当当客户端有文件上传时，通过该数组提供的信息，你可以做你想做的事情
ftp、curl 上传，都是将 php 作为客户端，想远程服务器提交数据
为什么要模拟登陆呢？
如果对方是自己的，模拟的意义何在呢？
如果对方不是自己的，那么是否有盗窃之嫌呢？
1、$_FILES 是通过表单上传文件，上传的文件信息保存在$_FILES中，php可通过move_uploaded_file()函数来完成文件上传，一般有个用户动作
ftp、curl 上传，是用php脚本向远程服务器上传文件。
2、就看手册介绍吧
