Ajax-implemented in PHP similar to logging in Renren: You have an X-ray or a real-time tip in the top right corner like Sina Weibo.

It is said that the front desk uses Ajax, followed by PHP processing database ....

The front end is a JavaScript implementation, and using jquery can simplify some of the following:

$.get (  '/getnewreply.php ',  {uid:uid}  function (data) {    //update the contents of HTML, according to data  });

On the server side, getnewreply.php to implement the query database:

$sql = "SELECT count (id) from replies where uid={$_get[' uid ']}"; $r = $db->execute ($sql); Echo Json_encode ($r);

Code like this, but you need to modify the code based on your database and others.
