PHP - $_SERVER['QUERY_STRING'] has "&"

Question

In my php script, I'm trying to get the query string ($_SERVER['QUERY_STRING']), append it to another url, and then make a redirect.

If I use the query string without any processing, the new url shows "& amp;" for all the "&'s." Therefore the new url won't work.

I print out the $_SERVER['QUERY_STRING'] and view the page source. It does use "& amp;" for all the "&'s." It doesn't make sense to me and I wonder why. Is it just my server's configuration or PHP's default?

UPDATE: I tested it on MODX CMS using snippet. If running on a regular PHP script, there is no such issue. I guess the problem is with MODX. Any idea?

If modx is what is causing the issue, why not generate the query string yourself? Try echo http_build_query($_GET) and see if it produces the same result. — Dave Chen

It's simple to achieve what I want, but I'm curious what could cause this. — Shawn

Just an idea: If you use TinyMCE to edit stuff, it changes all &'s to &'s - that has been driving me crazy for a lot of times. That happens in snippet calls and can be debugged if you either deactivate the rich text editor for a resource or "quick edit" a resource.

Also good practice: put snippet calls into a chunk. You can call that chunk without risking the syntax of the snippet call.
