How to use comma in URLs

[AQuser]

It's possible to use comma's in URLs for example: ?page=$page&id=120

Instead of AND (&) we use comma

?page=$page,id=120

[Atli]

That should work fine. A comma is not a special char in URLs so it should come through as a part of the "page" value.

[AQuser]

Can you give me an example for this to replace & (and) with , (comma)

[Dormilich]

as far as I know, this needs your server to rewrite the url containing commas back into ampersands. in contrast to & (parameter separator), the comma does not have a special meaning. otherwise you’ll only get one URL parameter (page).

Or, you could convert it in PHP.

if (!empty($_GET) && count($_GET) == 1) {
    $query_vars = array();
    $query_data = explode(',', current($_GET));
 
    if (!empty($query_data)) {
        $query_vars[key($_GET)] = array_shift($query_data);
 
        foreach ($query_data as $query_pair) {
            if (!empty($query_pair)) {
                $query_pair = explode('=', $query_pair, 2);
 
                if (count($query_pair) == 1) {
                    $query_vars[$query_pair[0]] = null;
                } else {
                    $query_vars[$query_pair[0]] = $query_pair[1];
                }
            }
        }
    }
 
    $_GET = $query_vars;
}

Untested.

I found this idea interesting, and decided to write something a bit more concrete to solve your problem. I've explained it in more detail here.

/**
 * Rebuild the superglobal $_GET array
 *
 * @param string $query_string The query string
 * @param string $ampersand The replacement for ampersands in the query string
 * @param string $equality The replacement for equality signs in the query string
 * @return void
 */
function rebuild_get($query_string, $ampersand = '&', $equality = '=') {
    if (!empty($query_string)) {
        // Empty the $_GET array
        $_GET = array();
 
        // Insert key => value pairs into the $_GET array
        foreach (explode($ampersand, $query_string) as $pair) {
            $pair_data = explode($equality, $pair, 2);
            $_GET[$pair_data[0]] = (count($pair_data) > 1) ? $pair_data[1] : null;
        }
    }
}

Why do you want to use a comma instead of an ampersand? AFAIK, the valid separators are ampersands (&) and semi-colons (;).
