I need to a while Once every 4 seconds checking new message in file db.php

Sample :

function while_check_seen()
{
    $(".replay").delay(4000).load("../db_pms.php?action=check");    
    while_check_seen()
}

This while worked, but used a lot of CPU!

Can anyone suggest a better way?

You can try this:

setInterval(function() {
    $(".replay").load("../db_pms.php?action=check");    
}, 4000);
