i think this is a bit of a noob question, but here goes.
I am trying to get a better understanding $_GET variables in PHP. A lot of CMS's etc convert things like site.com/?ID=42 into something like site.com/42
My question is, what happens to the $_GET variables when this happens? I try and print the GET array on page load, and it is empty.
分享 If you pass arguments this way, they will no longer be GET variables as they are not passed using the traditional ? GET syntax. They are just part of the URL, which will be parsed by the "CMS" framework you are using.
However, if you happened to pass a "traditional" GET variable and want to read it on the server, you would have to consult the CMS's documentation. If the framework is going to use pretty URL's it will probably also remove any GET variables, as they are no longer necessary. For example, the CodeIgniter MVC framework (not a CMS on its own, but may used to build them) does this.
