PHP is a server side language, and only ways you are going to send request to the server, are through redirection, navigation, refresh or through an ajax request.
PHP 是一种服务器端语言，您将请求发送到服务器的唯一方式是通过重定向、导航、刷新或通过 ajax 请求。
So, You will need Javascript for that.
因此，您将需要 Javascript。
Here is a simple demo
这是一个简单的演示
setInterval(function() {
var currentTime = new Date ( );
var currentHours = currentTime.getHours ( );
var currentMinutes = currentTime.getMinutes ( );
var currentSeconds = currentTime.getSeconds ( );
currentMinutes = ( currentMinutes < 10 ? "0" : "" ) + currentMinutes;
currentSeconds = ( currentSeconds < 10 ? "0" : "" ) + currentSeconds;
var timeOfDay = ( currentHours < 12 ) ? "AM" : "PM";
currentHours = ( currentHours > 12 ) ? currentHours - 12 : currentHours;
currentHours = ( currentHours == 0 ) ? 12 : currentHours;
var currentTimeString = currentHours + ":" + currentMinutes + ":" + currentSeconds + " " + timeOfDay;
document.getElementById("timer").innerHTML = currentTimeString;
}, 1000);
