php-messenger
A proof of concept web messenger using PHP and MySQL.
This project was part of a "Internet Technologies" course to demonstrate PHP, MySQL, JSP and CSS working all together.
Beware !
This is just a proof of concept. The database query frequency, timings and queries themselves used in this project are inefficient.
