根据出生日期[不基于用户输入]计算年龄（jQuery或PHP） [英] Calculate age (jQuery or PHP) based on date of birth [not based on user input]

问题描述

我正在寻找一个JavaScript或PHP脚本，允许我根据他/她的出生日期以 mm / dd / yyyy 格式计算某人的年龄。我发现这个非常有用的链接用JavaScript计算年龄但它似乎是为了工作而设计的用户输入。但是，我正在创建一个页面，我将DOB直接放入HTML作为简单文本。那么还可以计算年龄吗？基本上，我希望这行文字是最终结果：

I am looking for a JavaScript or PHP script that allows me to calculate somebody's age based on his/her date of birth in the mm/dd/yyyy format. I found this very helpful link "Calculate age in JavaScript" but it seems to be designed to work with user input. However, I am creating a page where I put the DOB directly into the HTML as simple text. Is it then still possible to calculate the age? Basically, I want this line of text to be the end-result:

29 (10/17/1983)

值为 29 自动计算并显示为多年的年龄。

with the value of 29 being automatically computed and displayed as the age in years.

如果这样的事情可能发生，我将非常感谢你的帮助。我对PHP和/或jQuery非常熟悉，但我当然不是高级专家。

If something like this is possible, I would be very grateful for your help. I am fairly familiar with PHP and/or jQuery but I'm certainly not an advanced pro.

推荐答案

PHP：

$today = new DateTime();
$birthdate = new DateTime("1973-04-18 09:48:00");
$interval = $today->diff($birthdate);
echo $interval->format('%y years');

在行动中看到它。显然，您可以根据自己的需要对其进行格式化。

See it in action. You can obviously format the out to suit your needs.
