Well thats Linux not Windows. mssql_connect() is only availible on Windows. reason being is that Linux cannot run mssql server. Same reason why Windows cant run certain Linux applications. Linux was mainly made for the Web hosting industry not Game Server. Many game servers use Windows Server 2000 Pro or Windows Server 2003 Enterprise to host their servers. Only very few games Require Linux. and they will use mysql. Now do you understand?
Wrong.
U don't have mssql extension enabled. to enable it on Linux u have to recompile php.
