I thought that some of you might find it useful to learn how to generate a random string or a random number with PHP. I wrote a quick function to use PHP to generate random. See it below :

function genRandomString() {
    $length = 10;
    $characters = ’0123456789abcdefghijklmnopqrstuvwxyz’;
    $string = ”;    

    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, strlen($characters))];
    }

    return $string;
}
