title: Connect to old mysql server (4.0.20-standard) from php7
body: <p>I want to connect to old mysql server (Server is 4.0.20-standard) with php7. Upgrade mysql server or downgrade php is not an option.</p>
  
  <p>I'm doing this: <code>$conn = mysqli_connect($local,$user,$pwd,$db,$port);</code>
  But i'm getting this error: <code>Warning: mysqli_connect(): Connecting to 3.22, 3.23 &amp; 4.0 is not supported. Server is 4.0.20-standard</code>.
  Is possible do that?</p>
