title: SQL Server instead of MYSQL in WAMP
body: <p>We have an application which uses WAMP server. Now, there is a new requirement from a customer who wants to use MS SQL Server instead of MySQL.
  How easy is it to port to SQL Server from MySQL. Also it has to retain this configuration.
  Apache->PHP->SQL Server on windows.
  How can I connect from Apache to SQL Server. Hope PHP works well with SQL server.</p>
  
  <p>Please advise.<br>
  Thanks,<br>
  Vish</p>
