根據出生日期計算年齡（jQuery或PHP）[不基於用戶輸入]

我在尋找一個JavaScript或PHP腳本，它允許我根據他/她的出生日期計算出某人的年齡爲mm/dd/yyyy格式。我發現這個非常有用的鏈接「Calculate age in JavaScript」，但它似乎被設計爲與用戶輸入一起工作。但是，我正在創建一個頁面，將DOB直接放入HTML中作爲簡單文本。是否仍然有可能計算年齡？基本上，我想這行文字是最終結果：根據出生日期計算年齡（jQuery或PHP）[不基於用戶輸入]

29 (10/17/1983)

與29價值被自動計算，並隨着年齡的年顯示。

如果這樣的事情是可能的，我會非常感謝您的幫助。我對PHP和/或jQuery非常熟悉，但我當然不是高級專業人員。

PHP：

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

See it in action。你顯然可以設計出適合你的需求。

這不會工作，如果我的生日，它的00:00:00和09之間： 47:59。您需要將時間設置爲00:00:00 – Waygood 2013-03-18 13:00:01

非常感謝！還有一個問題，這個函數是閏年的嗎？ – rf2012 2013-03-18 13:28:41

它的確如此。 DateTime類自動處理大量日期/時間怪癖，如閏年。 – 2013-03-18 13:36:33

的Javascript：

這可能真的比你多問，但會給你的年，月，日和年齡。

像這樣：8 years, 7 months, 21 days old

這種運作良好，如果你有一個網站只有幾天大新生。

這事近9年前，我在我女兒的網站使用

function GetMyAge() 
{ 
<!-- 

birthTime = new Date("July 25, 2004 00:00:00 GMT-0600") 
todaysTime = new Date(); 

<!-- Parse out specific date values 
todaysYear = todaysTime.getFullYear() 
todaysMonth = todaysTime.getMonth() 
todaysDate = todaysTime.getDate() 
todaysHour = todaysTime.getHours() 
todaysMinute = todaysTime.getMinutes() 
todaysSecond = todaysTime.getSeconds() 
birthYear = birthTime.getFullYear() 
birthMonth = birthTime.getMonth() 
birthDate = birthTime.getDate() 
birthHour = birthTime.getHours() 
birthMinute = birthTime.getMinutes() 
birthSecond = birthTime.getSeconds() 

<!-- Adjusts for Leap Year Info 
if ((todaysYear/4) == (Math.round(todaysYear/4))) { 
    countLeap = 29} 
else { 
    countLeap = 28} 

<!-- Calculate the days in the month 
if (todaysMonth == 2) { 
    countMonth = countLeap} 
else { 
    if (todaysMonth == 4) { 
     countMonth = 30} 
    else { 
     if (todaysMonth == 6) {

       if (todaysMonth == 11) { 
       countMonth = 30} 
       else { 
       countMonth = 31}}}}} 

<!-- Doing the subtactions 
if (todaysMinute > birthMinute) { 
    diffMinute = todaysMinute - birthMinute 
    calcHour = 0}

    diffMinute = todaysMinute + 60 - birthMinute 
    calcHour = -1} 
if (todaysHour > birthHour) { 
    diffHour = todaysHour - birthHour + calcHour 
    calcDate = 0}

在javascript中你可以計算出它：

function getAge(dateString) { 
    var today = new Date(); 
    var birthDate = new Date(dateString); 
    var age = today.getFullYear() - birthDate.getFullYear(); 
    var m = today.getMonth() - birthDate.getMonth(); 
    if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) { 
     age--; 
    } 
    return age; 
}

計算年齡的最簡單方法是：

CURRENT YEAR - BIRTH YEAR = AGE 
IF(CURRENT MONTH DAY < BIRTH MONTH DAY) AGE--;

IE年還活着，但-1，如果您還沒有一個生日尚未

月日是0301 3月1日
