[Resolved] Pass PHP Array in the URL?

[The Hobo]

I'm calling a page like this: http://localhost/test.php?a[]=a&a[]=b&a[]=c&a[]=d&a[]=e&a[]=f&a[]=g&a[]=h&a[]=i

And using this code:

    <?php
        if (isset($_REQUEST['a'])) {
            if (is_array($_REQUEST['a'])) {
                for ($i = 0; $i < count($_REQUEST['a']); $i++) {
                    echo $_REQUEST['a'][$i] . '<br />';
                }
            }
        }
    ?>

It works perfectly, but I'm wondering if there are any drawbacks to it?

I've never seen anything do it this way before, so it makes me paranoid that there's something wrong with doing it that way.

Only thing I can think of, is, is there a maximum length for a querystring?

Nothing wrong, it's a feature of PHP.

Cool. Thanks, guys.

Would it not make more sense to pass complicated data like that by POST instead of GET?
