From what I’ve read, it seems that $_SERVER['REQUEST_URI'] won’t always return query strings properly, but does anyone have a good sense of what the success rate is? Will it work in the majority of cases for the average client?

What, if anything, would cause REQUEST_URI to not be populated or not include the query string?

    You asked:

    Answers that I can think of:

    1. The web server provides all the $_SERVER values to PHP, so if the server doesn’t provide them, then they won’t be set. This is highly unlikely with any decent web server, but is possible.

    2. If you run a PHP program from the command line, it won’t have any $_SERVER values. (in case you’re not worried about this, bear in mind that unit tests are typically run from a command line, so it does matter if you’re following best practices and writing unit tests)
