PHP script for email validation

[Livewirez]

Does anybody know where to find a php script (for idiots! ie me) that validates email addresses when entered into a form.

Any info would be appreciated
cheers

if you are just looking to make sure it matches the pattern for emails you could use this

$pattern = '^([._a-zA-Z0-9-]){2,255}@([._a-zA-Z0-9-]){2,255}\.([a-zA-Z]){2,3}$';
if (!ereg ($pattern,$email)) {
echo "bad email";
}
