laravel validate email of user editing email code example

Example 1: laravel using username instead of email

All we need is add a method in app/Http/Controllers/Auth/LoginController.php:

/**
 * Get the login username to be used by the controller.
 *
 * @return string
 */
public function username()
{
    return 'username';
}

Example 2: laravel check if email is real

<?php
$email = "[email protected]";

if (filter_var($email, FILTER_VALIDATE_EMAIL)) {
  echo("$email is a valid email address");
} else {
  echo("$email is not a valid email address");
}
?>
