title: Unable to connect to SQL Server with PHP
body: <p>Connection to <code>sqlsrv</code> string not working. </p>
  
  <pre><code>$login = new PDO("sqlsrv:server=MYSQLSERVER\SQLEXPRESS;Database=db_name", "user", "passw");
  </code></pre>
  
  <p>And i have error message:
  <code>Fatal error: Invalid handle returned</code>.</p>
  
  <p>I'm 101% sure that login details is OK. Because it works on other projects. Could be a problem <code>PHP 7</code>?</p>
