is PHP fast enough to transmit heavy data traffic?

Question

i'm developing a chat program in PHP where more than 500 users to be connected per day. plus it would own file transfer function as well thus the program must be fast enough. so i wanna know if the PHP is fast enough to accomplish this job or i must use other one platform??

Answer 1

Yes, PHP is fast enough. The only variable here is your coding skill (and if the number of users really gets out of hand, your server configuration) - if you make the chat program well, there shouldn't be any problems.

It is imperative you give your tables good indices, and that you optimize your queries. When done properly, a PHP chat can support thousands of concurrent users with almost no impact on performance.
