Chats are used on various Internet resources to communicate between users. To write a simple chat script, you will need to implement the registration procedure, write the script code itself, and set up a user-friendly interface.
It is necessary
local Apache server with PHP and MySQL
Instructions
Step 1
Before writing a script, think carefully about all its components. Decide what functionality you would like to implement in this program, how it will save data and perform text output. For example, in order to arrange for automatic updating of records in the browser window without having to refresh the entire page, you will have to resort to using Ajax. Design the initial code, and then start writing it.
Step 2
First, you need to implement the registration procedure to use the script. It is better to use the MySQL database to save the registered users. Create a database on your localhost via phpMyAdmin and start writing some code that can be implemented in PHP. For a regular registration script, you will need to output an HTML form, the data of which will be processed through PHP and written to the MySQL database.
Step 3
After writing the registration page, you will need to do authorization, after which you can make the display of chat functions available. The principle of the script is that the user enters his username and password in the appropriate field on the page. After clicking the button, HTML passes the processing to a script that checks for the presence of user-specified data in the MySQL database. If the verification is successful, the chat elements are loaded. If not, the script stops working and the user goes back to the login and password entry form.
Step 4
Start writing the interface of the chat itself. Create a separate file and include it on the login page via the include statement. Create MySQL tables that will store posts as well as username and post time. Use the jQuery library to build a self-updating page after each chat entry appears. To implement this function, you can create a loop to display the written text with an update every 2-3 seconds. After that, build a handler and organize the output of messages in the program window.
Step 5
After finishing writing the program, edit the resulting code and run it for debugging on your local server. If the script is functioning properly, you can add additional options to it, such as spam protection or clearing the message window. After writing all the code, you can edit the chat design and upload it for testing on the hosting or server where your resource is located.
