title: Why is important to reopen a connection to mysql?
body: <p>I have seen programmers that to this in the same doc: </p>
  
  <pre><code>$connection = mysql_connect("localhost","user","password");
          $request = "firts request";
          mysql_query( $request , $connection );
          mysql_close( $conexion );
  $connection = mysql_connect("localhost","user","password");
          $request = "second request";
          mysql_query( $request , $connection );
          mysql_close( $conexion );
  </code></pre>
  
  <p>The question is what if I do not close the connection?</p>
