email validation

[[deleted]]

after sifting through the email validation banter/requests/discussions on this forum i decided i was still not finding the information i am looking for...

i know a decent amount about php, so can someone tell me why:

!eregi('^{[A-Za-z0-9_-]+@[A-Za-z0-9_-]+.[A-Za-z0-9_-]+.*',} $email))

...does not seem to work in my script?

here is the script, and i'm trying to use it as an include:

<?php
function valid_email ($email)
{
$name = cleanup_text($name);

if (empty($email)) || !eregi('^[A-Za-z0-9\_-]+@[A-Za-z0-9\_-]+.[A-Za-z0-9\_-]+.*', $email))
{
    $errmsg .= "<SPAN CLASS=bold>$email does not appear to be a valid email address.</SPAN>\n";
}

}
?>

thanks for any tips you may have!

[idiotproof]

it may (prob is) because php has a habit of putting \ in front of special charachters. look up the php command 'stripslashes'

"." character is special for regular expressions , so you should disable its meaning by putting '\' in front of it. That is :
!eregi('^{[A-Za-z0-9_-]+@[A-Za-z0-9_-]+.[A-Za-z0-9_-]+.*',} $email))

I hope this will work.
Good luck
