le-chat-php | A PHP Chat based on LE CHAT | Chat library

You'll need to have php with pdo, pcre, mbstring and date extension, and a web-server installed. You will also need the pdo_sqlite, pdo_mysql or pdo_pgsql extension, depending on which database you choose. Optionally, you can install:.
the gd extension for the captcha feature
the json extension for save/restore
a memcached server and the memcached extension and change the configuration to use memcached. This will lessen the database load a bit.
a MySQL or PostgreSQL server to use as an external database instead of SQLite
the libsodium extension (PHP >= 7.2) for encryption of messages and notes in the database When you have everything installed and use MySQL or PostgreSQL, you'll have to create a database and a user for the chat. Then edit the configuration at the bottom of the script to reflect the appropriate database settings and to modify the chat settings the way you like them. Then copy the script to your web-server directory and call the script in your browser with a parameter like this: http://(server)/(script-name).php?action=setup Now you can create the Superadmin account. With this account you can administer the chat and add new members and set the guest access. As soon as you are done with the setup, all necessary database tables will be created and the chat can be used. Note: If you updated the script, please visit http://(server)/(script-name).php?action=setup again, to make sure, that any database changes are applied and no errors occur.
