So I'm sure you all know about Cleverbot, it's obviously a web application, however, my question is, what server side languages are capable for creating such a complex application? Would it be too much for, say, PHP?
Edit: By "too much" I mean will PHP slow down the server running it considerably compared to another language. The server would be something typical perhaps 256MB of ram and a dual core processor.
Duplicate of https://stackoverflow.com/questions/82036/what-is-a-good-programming-language-for-ai - There is no "best" - it depends on what you want todo, a stupid web bot, why not php it would be okayish but not perfect. As soon as it becomes complex, i would not recommend php anymore.
Performance wise we canot predict how you code will look like, what data you want to crunch etc etc. Just keep in mind php is and never was made for long running processes.
