title: mysql_connect can not work in remote server in stead of local server
body: <p>I got such warning :</p>
  
  <pre><code>Warning: mysql_connect(): Headers and client library minor version mismatch. Headers:50537 Library:50617
  </code></pre>
  
  <p>when try to upload my code to my remote server, and my remote server currently using php 5.5
  , It's because the mysql extension has been already deprecated so that i have to change the extension to mysqli?
  but in my local server, i tested in php 5.5 too and it works as normal</p>
  
  <p>what would be the issue here?</p>
