The installation instructions are the same as that of Custom PHP Site. However, before proceeding to them, please make sure that you have configured your server.

No modifications are required to your existing ASP or .NET site code.

Please create a support ticket for the PHP + MSSQL version of CometChat. The default adapter is PHP + mySQL.

Server Setup

• Install PHP on your IIS server using the tool at http://php.iis.net
• Install the SQLSRV driver for PHP to allow PHP to connect to MSSQL from http://www.microsoft.com/sqlserver/2005/en/us/php-driver.aspx

Code Modification

The only modification that needs to be performed in your existing ASP or .NET code is to add a cookie like userid when the user logs in and reset it to 0 when the user logs out.

Follow Custom PHP Site Instructions

Once that above is completed, follow the installation instructions for custom PHP site.
