title: Install SQLSRV extension for PHP on WAMP
body: <p>I've seen many of these posts and have looked through them all, but I still cannot get the SQLSRV extension running.  Can you help me out?  I will post all the information I have below:</p>
  
  <ul>
  <li>Windows 7 64-bit</li>
  <li>WampServer 2.2 32-bit</li>
  <li>PHP 5.4.3 32-bit</li>
  <li>Apache 2.2.22 (can't tell if VC6 or VC9)</li>
  <li>Microsoft SQL Server 2012 Native Client 64-bit</li>
  </ul>
  
  <p>I downloaded SQLSRV30.exe.  I extracted the dll files to C:\wamp\bin\php\php5.4.3\ext.</p>
  
  <p><strong>In my php.ini:</strong><br /></p>
  
  <ul>
  <li>extension_dir = "c:/wamp/bin/php/php5.4.3/ext/"<br /></li>
  <li>extension=php_sqlsrv_54_ts.dll<br /></li>
  <li>extension=php_pdo_sqlsrv_54_ts.dll</li>
  </ul>
  
  <p>I know that SQLSRV30.exe is built as 32-bit.  This is why I have 32-bit versions of Wamp and PHP.  I also know that nothing in Wamp is non-thread-safe.<br />
  If I view phpinfo() I should see a 'sqlsrv' section, but I currently do not.<br /><br />
  What am I doing wrong?</p>
