pattern matching

[Rain Designs]

I know this is a pretty basic question, but I couldn't find any good documentation online, nor in this forum. So heres my question: How would I check to make sure the user input an email address. I'm guessing something like this:


if ($_POST["email"] == '/\\s*@\\s*.\\s*')


???? thats gotta be wrong, I'm trying to remember perl expressions from way back when :D

Thanks for the help,
Alex

if (!eregi ("^([a-z0-9_]|\\-|\\.)+@(([a-z0-9_]|\\-)+\\.)+[a-z]{2,4}$", $email) {
echo "Not a valid email" ;
}
else {
echo "Valid email" ;
}

many ways to do it.


if (!preg_match('/^[-!#$%&\'*+\\.\/0-9=?A-Z^_`{|}~]+@([-0-9A-Z]+\.)+([0-9A-Z]){2,4}$/i', $email)) {
$errmsg = "Sorry your email is invalid, please try again";
}


tonto: using the php code tags strips most of that reg exp out.
