如何自动更新PHP日期和时间

Question

我有一个显示日期和时间的脚本.

如何添加内容以使其自动更新而不是页面刷新.

这是脚本:

<?php
$hourdiff = 0; // Replace the 0 with your timezone difference (;
$site = date("l, d F Y g:i a",time() + ($hourdiff * 3600));
echo $site;
?>

谁能帮忙.谢谢.

PHP是一种服务器端语言,只有通过重定向,导航,刷新或通过ajax请求才能向服务器发送请求.

所以,你需要Javascript.

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);
