Bu yazıda php kodlama diliyle bir forum nasıl kodlanır onu anlatmaya çalışacağım. Adım adım uygularsanız işlem sonunda basit bir forum scripti elde etmiş olacaksınız. Bu forumu geliştirmek size kalmış. Bu bir başlangıçtır ve mantığını kavrama amaçlı verilmiştir. Gelişmiş özellikler eklemek sizin kodlama bilginize kalmıştır. Hadi başlayalım canlarım... ilk Önce Tablolarimizi Olusturuyoruz; Katagori Tablolari
