使用php连接到灯服务器上的数据库

I have a database on a lamp server and want to connect to this database with a windows 7 pc from my home and use queries.

With putty I can connect with the server with ssh. First connect with ssh, then connect to the mysql database.

In php do I need to use ssh2 libraries like phpseclib and connect trough ssh2 and use the interactive shell or is there a way to connect with the database directly. Thus skipping the shell?

Thanks.

Take a look at this:

<?php
  $connection = mysql_connect("localhost","root_user","root_password")
         or die("problems connecting to DB.");

  mysql_select_db("my_database",$connection) 
         or  die("Problems selecting DB.");

  $records = mysql_query("select id, name, school from students",$connection) 
         or die("Problems on querying " . mysql_error() );

  while ($record = mysql_fetch_array($records)) {
    echo "id: " . $record['id'] . "<br>";
    echo "name: " . $record['nombre'] . "<br>";
    echo "school: " . $record['school'] . "<br>";
  }
  mysq_close($connection);
?>
