Oluşturduğunuz projenize birçok sebepten ötürü, ülkelerden girişleri engellemek isteyebilirsiniz. Bu en doğal hakkınız. Fakat bu işlemi .htaccess üzerinden takip etmeyi denediğinizde, ülke bazlı IP class’larının sık sık değiştiği için zamanla işe yaramadığını görebilirsiniz. Bu da sizin IP bloklarını sık sık güncellemeniz anlamını taşır. Bunun yerine daha pratik bir çözüm geliştirdik. Aşağıdaki kod bütünü sitenizi ziyaret eden IP’nin anlık sorgusunu yaparak ülke koduna ulaşıyor ve sizin yasaklı listenizde ise, ziyaretçiye 403 Engel yanıtını gönderip çalışmayı durduruyor.

Aşağıdaki satırları, index.php veya ortak kullanılan (örn: config.php gibi) PHP dosyanızın en üstüne, <?php satırının hemen altına ekleyebilirsiniz:
