AJAX is probably the simplest solution. You can perform an AJAX request on the same page your PHP code is executing on if you really want to.

(function check() {
    $.get('mypage.php', function(data) {
        doSomethingWith(data);
        setTimeout(check, 5000); // every 5 seconds
    });
})();
