How to install and configure phpMyChat, an easy-to-use, multi-room PHP, and DB chat system. 


Although phpMyChat-Plus provides an automated installation utility, it is recommended that you install the program manually, according to the instructions provided below.

What you need

  • A Nexcess account on a physical (non-cloud) server.
  • An existing SiteWorx account, with permissions to create MySQL Databases enabled.
  • The ability to connect to your hosting account via FTP.

1: Download phpMyChat

  1. Download the latest version of phpMyChat.

  2. Save the .zip file to your local drive, and then extract the file using a compression utility.

2: Create a MySQL Database

Follow the steps below to create a MySQL database, via your SiteWorx account. This database will be used specifically for phpMyChat-Plus.

  1. Log in to your SiteWorx account.
  2. From the SiteWorx main menu, click Hosting Options > MySQL > Databases.

    In the Database Name field, type a name for the new database, do not use spaces but underscores are acceptable.

    ATTENTION: SiteWorx will automatically prefix the database name with the first eight characters of your domain name. For example, if your domain name is "" and you assign "my_database" as the database name, the assigned name will be "examplec_my_database".

    Select the Create User check box. The page automatically expands and displays additional fields for creating the user login information, as well as check boxes for selecting the access permissions that you will assign or not assign to the user.

    Type a username and password or click Generate to have one automatically created.

    Click Add.

3: Modify the configuration file

  1. Navigate to the following location on your local drive: /plus/config/config.lib.php.

    ATTENTION: Under the Database settings section, only modify the first three lines.

    ATTENTION: Notice that the first eight characters of the domain name is prefixed to the database name and database user line items.

    • define(" C_DB_NAME ", 'examplec_chat');
