Which is better to use node or php for chat?

Question

PHP

The crux of the matter is even this, the project is not all devoted to chats, that is, if only the nodes are frequent, and here chats are one of the large modules, but not the whole project. That is, the functions of a standard site with a database plus Chats (on sockets ). so which is better node or php? The question is specific, and not just a ko-ko on the topic: "Cooler node or php", so please also give specific answers

Answer 1

The answer is specific: node, namely meteor. Google it and marvel at how this technology is suitable for chats.
