title: How to enable php_mssql and php_pdo_mssql
body: <p><br>
  I have an old project that uses php_mssql and php_pdo_mssql and I want to run it on a wamp server with PHP 5.5.12. I downloaded the following dlls:</p>
  
  <ul>
  <li>php_mssql.dll (wamdir\bin\php\php5.5.12\ext)</li>
  <li>php_pdo_mssql.dll (wamdir\bin\php\php5.5.12\ext)</li>
  <li>ntwdblib.dll (wamdir\bin\php\php5.5.12)</li>
  </ul>
  
  <p>I added the following lines to php.ini:</p>
  
  <pre><code>extension=php_mssql.dll
  extension=php_pdo_mssql.dll
  </code></pre>
  
  <p>And finally enabled the php_sybase_ct extension (read it somewhere)<br>
  Though I can see php_mssql and php_pdo_mssql checked in php extensions list in wamp, the extensions doesn't work and it gives this error when I test it:</p>
  
  <pre><code>Fatal error: Call to undefined function mssql_connect() 
  </code></pre>
  
  <p>I run <code>phpinfo();</code> and I can't see php_mssql and php_pdo_mssql anywhere.</p>
  
  <p>Please Help.</p>
