XYZ Chat System Using PHP and MySQL

Communication is one of the most aspect of our human life as we are born in this world. We have learned how to communicate by gestures, hand signal and the language that is being taught to us by our parents.  There are thousands of languages and dialects all over the world that makes communication with other people more difficult and needs most of the time a translator just to translate one language to another language. One of the official language the is being spoke by millions of people around the world is the English language. The language itself is very universal the most text books and novels are being written using the English language.

Because of our shrinking world now a day’s communication becomes more easier compared to the past. I still remember during my early age my parents teach us how to write a letter and drop the letter to the post office. That’s the time the Internet is not widely used nor not yet existing in our country here in the Philippines.  By mid 1990’s the introduction of the Internet in our society paved way to a new method of communication the use of email, chat, text, voice over IP and video conferencing becomes a common medium of communication among us. It makes our communication to our friends, family members and relatives more efficient and best of all cost less. The interaction is in real time so there’s no need for us to wait for weeks or months just to receive the reply letter or message.

In this article I will teach you and discuss how to make a chat system using PHP and MySQL. When I have learned how to use mIRC, Yahoo Messenger and more recently chat system in Facebook I have also some questions in my mind how to create my own chat system. As I said before the use of Internet as source of information is very common now a days and very beneficial after some research I find some codes and try to improve and add functionality the is suited in my needs. That’s I came out with the program called XYZ Chat System 1.0 Using PHP and MySQL.  In writing the code I started with the use of HTML,CSS for the framework and layout of my page. After that I use JQuery  to refresh my page is every 1 second and finally the use of PHP and MySQL to save the messages in our database.

What the program will do is very simple I will ask the user to enter the name of the person below is a text field where all the conversation will be display to the end user and finally a text file where the user type the message and by clicking the send message it will display the message of the screen and save the message including the name of the sender in our MySQL database so we can monitor and retrieve whatever conversation that our user has in our system. This program is very simple there are still many things that can be done just to improve its overall functionality in general.

I test the chat system in my localhost it means in one computer and a LAN network. If you like to test this program in a LAN network my advice is for your mapped first the server computer and assign its IP address and for the of the client computer you also assigned a different IP address for example let say the server IP address is 192.168.20.10 when we access our program via the web browser we can use a command like this http://192.168.20.10/chat/index.php as simple with this command we can access of chat system that is being mapped in our windows operating system.

Employee's Information System in C++

Here is a very simple employee's information system that I wrote using C++ in a very long time ago when I am still teaching in the University here in my hometown in Bacolod City.
