    Yes, Synchronium is right, each variable of the query string (after ? mark) is accessible by GET request.

    For example if you have url.php?a=1&b=2&c=3&d=pofapdopfosd
    then you will have a value for $_GET['a'], $_GET['b'], $_GET['c'] and $_GET['d']

    Bind, doing something like 
    
$numbers=array('zero', 'one', 'two', 'three', ...)
echo $numbers[$_GET['n']];
    PHP:
    would have been simpler, but your solution is good!

    agreed, but still have to parse for each charactor - strlen()+substr() - unless only one number is allowed per form submit.

    here they are combined if anyone is interested:

    
<?php
$numname = Array("zero ","one ","two ","three ","four ","five ","six ","seven ","eight ","nine ");
if (isset($_GET['n']))
    {
        for ($i=0;$i<=(strlen($_GET['n'])-1);$i++)
            {
                $character = substr($_GET['n'], $i, 1);
                if (strstr("01234567890",$character))
                    {
                        echo $numname[$character];
                    }
            }
    }
?>
<FORM method="GET" action="">
    <input name="n" type="text" /> -
    <input name="submit" type="submit" value="Submit" />
</FORM>
