OPINION : Check validity of email address

[Anonymous]

In HTML5 you can use

<input type="email" required name="email_address">

which saves lots of validation requirements.

Hope that helps,

I like K.I.S.S. (Keep It Simple Stupid) ->

$email = "john.doe@example.com";

if (!filter_var($email, FILTER_VALIDATE_EMAIL) === false) {
  echo("$email is a valid email address");
} else {
  echo("$email is not a valid email address");
}
