Newbie needs help with regular expression
|
|
|
| Hi,
Please can someone help regarding providing a regular expression for entering
a set of characters with letters, numbers, periods (.), hyphens (-), or
underscores (_) only.
I've got as far as this:
$pattern="^([_a-z0-9-]+)(\.[_a-z0-9-])$";
Thank you in advance.
Kind regards,
Raj (newbie)

| $patterns = "/[^a-z0-9.-_]/i";
if (preg_match ($patterns, $word))
echo "not allowed";
else
echo "allowed";

| I think you better use preg because faster than ereg. I heard that
ereg will be deprecated.
