Solid foundation, minor tweaks needed
This PHP chat application is a decent starting point. The core functionality works well; the AJAX integration is smooth and the Bootstrap styling is clean. I was able to get it up and running fairly quickly. However, there are a few minor bugs I encountered. Specifically, the user input field sometimes doesn't update properly after sending a message. Also, the error handling could be improved; a more user-friendly message would be helpful when a connection fails. It's functional, but a bit more polish would make it excellent. For the price, it's a reasonable buy if you're comfortable with a bit of tweaking.
