如何获得PHP $ _GET数组? [英] How to get PHP $_GET array?

问题描述

是否可以在$_GET中将值作为数组?

Is it possible to have a value in $_GET as an array?

如果我尝试发送与http://link/foo.php?id=1&id=2&id=3的链接，并且我想在php端使用$_GET['id']，那么该值怎么能成为数组?因为现在echo $_GET['id']返回3.它是标题链接中的最后一个ID.有什么建议吗?

If I am trying to send a link with http://link/foo.php?id=1&id=2&id=3, and I want to use $_GET['id'] on the php side, how can that value be an array? Because right now echo $_GET['id'] is returning 3. Its the last id which is in the header link. Any suggestions?

推荐答案

在PHP中执行此操作的通常方法是将id[]放在URL中，而不只是id:

The usual way to do this in PHP is to put id[] in your URL instead of just id:

http://link/foo.php?id[]=1&id[]=2&id[]=3

然后$_GET['id']将是这些值的数组.它不是特别漂亮，但是可以直接使用.

Then $_GET['id'] will be an array of those values. It's not especially pretty, but it works out of the box.
