// Usage examples $emails = [ "user@example.com", "invalid-email", "user@localhost", "user+filter@example.co.uk" ];

This checks that the email follows RFC 822/RFC 2822 standards – correct format, presence of @ symbol, valid domain characters, etc. It does not check if the domain actually exists. 2. Domain Validation (DNS Check) To verify the domain has valid MX (mail exchange) records:

// Validate format if (!filter_var($email, FILTER_VALIDATE_EMAIL)) return ['valid' => false, 'message' => 'Invalid email format'];

return ['valid' => true, 'message' => 'Email is valid'];
