Hi Philip,
Yes, I have a choice of PHP3 or 4 and this script happened to be in PHP 3 so
I just tweaked it. I didn't realize that one day
$chars[mt_rand(0,$chars_len)] would "no longer work", but at least it is
backwards compatible now. I've made a mental note of that for future
reference.
PHP 3 also barked at
is_numeric()
which I just changed to intval()
I should really do better bounds checking. How about:
$len=intval($len);
if (!$len) $len=8;
kind regards,
bill
