The most common validation that we encounter is email address verification. Common on the site. Various web scripts are also commonly used in "regular expression" (regular expression) to verify the email address we entered, to determine whether it is legal.

does not prove that it must be valid. For this reason, some websites have taken the email password, special resources URL, etc., or ask the user to reply to email, to ensure the validity of the email address. However, these methods are not always effective, for example, you may not collect user emails from your own we
