title: "Premature end of data" error with PHP
body: <p>I've just started using WAMP for a PHP project and I get the next errors related with this line of code:</p>
  
  <pre><code>$link=mysql_connect("localhost","myuser","mypas");
  </code></pre>
  
  <p>I read that I had to do the SET PASSWORD again with my old password, but it still does not work after restarting all services. I am using PHP 5.3.4 and MySQL 5.1.53 Any help? THANKS</p>
