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.
I am currently accepting programming work kindly contact me in the following email address for further details. Thank you.
My email address are the following jakerpomperada@gmail.com and jakerpomperada@yahoo.com.
My mobile number here in the Philippines is 09173084360.
My telephone number at home here in Bacolod City, Negros Occidental is (034) 4335675.
