I have seen programmers that to this in the same doc: 

```
$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 );

```

The question is what if I do not close the connection?
