Validating e-mail address

[DeNasio]

Hello,

I'm using the following code to validate an e-mail address:

if (eregi("(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)|(\.$)|(\|)",$email) or !eregi("^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$",$email))
   {
   .......
   }

But the problem is that it does not work! I used to use this exact code in Perl and there it used to work fine.

Can anyone tell me why it does not work?

This is what I use...

<?php

$submit=1;

function check_email ($str) {
// Returns 1 if a valid email, 0 if not

if (ereg ("^.+@.+\\..+$", $str)) {
return 1;
} else {
return 0;
}
}



if (!check_email ($email)) {
$submit=0;
$email = "Invalid Email address";

}

?>

This checks the email submitted. If it was OK it returns a 1 and allows them to continue. If not, it says Invalid email address and offers a Back button to go and try again - this is the other code needed...

<?php

if ($submit) {

echo("<INPUT TYPE='submit' VALUE='Send Comments'>");

}

echo("<INPUT TYPE='button' VALUE='Go Back' ONCLICK='self.history.back();'>");

?>

Hope this helps...
