每个人都提到，PHP仅显示服务器端时间。

对于客户端，您将需要Javascript，以下方法可以解决问题。

var currentTime = new Date();
var hours = currentTime.getHours();
var minutes = currentTime.getMinutes();

if (minutes < 10) {
    minutes = "0" + minutes;
}

document.write("<b>" + hours + ":" + minutes + " " + "</b>");

而且，如果您想要AM / PM后缀，则应执行以下操作：

var currentTime = new Date();
var hours = currentTime.getHours();
var minutes = currentTime.getMinutes();

var suffix = "AM";

if (hours >= 12) {
    suffix = "PM";
    hours = hours - 12;
}

if (hours == 0) {
    hours = 12;
}

if (minutes < 10) {
    minutes = "0" + minutes;
}

document.write("<b>" + hours + ":" + minutes + " " + suffix + "</b>");
