Maybe you're doing something like this:

$email = "name@location.ext";

And only then you're inserting the contents of $email in the database. If so, @location will be interpreted, yes.

Ways to work around this:

• Escaping special characters: $email = "name\@location.ext";
• Single quoting: $email = 'name@location.ext';
• And other twisted ways: $email = "name@" . "location.ext"

The first one escapes the "@" sign, while the second one prevents variables from being interpreted inside the string.

The third one is just a proof that there is always another way... :-)
