Memo] Using php_mssql function in PHP 5.2.8 for Windows

When I installed PHP5.2.8, php_mssql function was not included. php_mssql function is already deprecated or obsolete, but there is a reason why I have to use php_mssql in PHP5.2 series. php_mssql.dll and ntwdblib.dll from php/ext/ directory of xampp1.7.1.

If you drop in PHP alone, php_mssql.dll is not included, but xampp includes php_mssql.dll.
