Can I have multiple $_GET with the same key, diffe

Question

Is it possible to retrieve the arguments from a url where the same $_GET has different values?

Such as www.domain.com/?user=1&user=2

Currently this only shows whatever is listed second, so if I echo $_GET['user'], it would output 2

I couldn't seem to find this on SO, so if I missed it please let me know.

Thanks for your help!

Answer 1

You could possibly use a foreach loop for each $_GET and then group all the 'user' variables into a single array and then access the whichever key value you need. 0 being the first, 1 being the second, and so on...

Answer 2

The query string gets parsed into the associative array $_GET, so when there are duplicated keys only the last version of the value is present on the map. You can however access the raw $_SERVER['QUERY_STRING'] and parse it on your own.

If possible, it would we best if you modify your code to not duplicate keys.

Answer 3

Yes, use user[] as key. should work. PHP access all $_POST[] variables into an array?

Answer 4

Quick answer is no.

http://localhost/?user=1&user=2

Gets you:

array
    'user' => string '2' (length=1)

However, by including brackets in the query like this:

http://localhost/?user[]=1&user[]=2

You can retrieve $_GET['user'] and be returned with this:

array
    'user' => 
        array
            0 => string '1' (length=1)
            1 => string '2' (length=1)
