Debug Modu?

Question

CodeIgniter, örneğin bir Geçersiz URL'ye erişirken bir Hata Ayıklama Modu sağlıyor mu?

Ruby On Rails, yanlış bir URL verildiğinde ve denetleyici, rota haritasını kullanarak bu sorunu çözemediğinde, hata ayıklama mesajlarını gösterir. CodeIgniter'de bu tür hata ayıklama iletilerini nasıl etkinleştiririm?

profil ...

$this->output->enable_profiler(TRUE); 

... sadece tek sınıfları etkiler, ancak tüm yolları. Yani gerçek bir hata ayıklama modu olmadan hata ayıklama biraz ... zor. :-)

Answer 1

profiler, bir hata ayıklayıcısından çok bir performans analizidir. Gitme yolu implementing very popular xDebug with CodeIgniter olacaktır. Yahya A. E.
