Encoding a PHP chat system is not difficult, but it requires a significant amount of code. The chat system effectively encoding need first to define the PHP chat module and its functionality. The PHP code must be data between a MySQL database and the client-side scripting software (such as JavaScript-ActionScript) designed form data and server variables.
Instructions
1. Definieren you the functionality of the modules of the PHP-chat application. Use the first PHP module to update the MySQL database with the IP address of the visitor, that have sent a chat. The second PHP module included in the code to send the latest chat submitted to all users that are currently stored in the chat-MySQL database.
2. Gehören in the first PHP module of PHP code to read the data in the text boxes of the form chat. Using the PHP "$ _POST ' global array variables get entered text in the chat form message text box and the user name that was entered in the chat form the user name text box. Use the "PHP $_SERVER" global array to store the user's IP address sent to the chat. Use "Mysqlconnect" PHP statement to connect to the database MySQL and PHP ' Mysqlquery ' statement with the MySQL database statement a "Update" to save the IP address, the user name, the chat message and time, received chat message was. to check
3. Gehören the second PHP module of PHP code, whether a new chat message has been received. We achieve this with PHP code that implements a sort on the field of "Id" in the MySQL database. To determine whether the last "id" in the way a smaller numerical value as the "id" of the currently submitted chat message has the PHP code. If the "id" of the currently submitted chat is higher than the "id" of all submitted chats using the PHP "Function Mysql_query" with "select" and "Paste" and "limit" options. Using PHP "mysql_fetch_array()" function to find, the records, the chat data that do not broadcast." Broadcast with the PHP "echo" statement of each chat message that was not sent.
