如何在不使用php / ajax重新加载网页的情况下自动更新内容？

I'm trying to create an auction tool using PHP. The problem I'm having (and I appreciate its a basic one but I need clarification) is that I don't understand how to update the "auction price" automatically on each users screen without them having to take any action or without causing a full reload of the page.

So far I understand that Ajax is used to do this but if anyone could point me in the right direction or to any useful materials. My plan for my project so far is to use PHP and JavaScript so any solution would need to be compatible with these languages.

Note: I'm using a MySQL database.

    Php/Ajax example:

    In this example you have index.html and record_count.php files

    Here is the Code:

    index.html contains the html code and javascript call to load record_count.php

    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript">
   var auto_refresh = setInterval(
      function ()
      {
         $('#load_tweets').load('record_count.php').fadeIn("slow");
      }, 10000); // refresh every 10000 milliseconds
</script>

<body>
     <div id="load_tweets"> </div>
</body>

    and record_count.php has the php code

    <?php
echo "some code or variable here";
?>

    you can change the javascript interval to suit your needs

    I'll leave you the blog link as a reference: 9lessons
