如何在我的Web应用程序中创建倒计时？ [重复]

I am trying get a counter to work in PHP so it basically counts '5' then '4' and so on till 0. It will redirect to a different page. I was just wondering how this can be done in PHP? if possible, if not what it would be in javascript?

setTimeout(function () {
       window.location.href = "newpage.html"; 
    }, 5000); //seconds
</script>
