每X秒自动运行一个PHP脚本，而无需刷新页面

Question

I have a website, and in the navigation header, I have a player count, for the people who are currently online (On an external server). The count is outputted as a raw number generated by PlayersOnline.php, and I just include that.

How would I have this page update the player count every X seconds without refreshing the page?

Answer 1

You can use Javascript and jQuery to solve this:

$(function() {
    updateCounter();
});

function updateCounter() {
    $.ajax({
        url: 'yourScript.php',
        success: function(output) {
            $('#yourCounterElementID').text(output);
        },
        complete: function() {
            setTimeout(updateCounter(), 5000);//run again in 5 seconds
        }
    });
}
