One way is a simple function that takes the length you want and the acceptable characters, something like this

function GenerateRandom($length, $charset='ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789')
{
    $randString = '';
    $count = strlen($charset);
    while ($length--) 
	{
        $randString .= $charset[mt_rand(0, $count-1)];
    }
    return $randString;
}

Hope that helps
