strtotime (PHP)

<?php
$date_now = date('Y-m-d', strtotime('+1 years'));
$date_now = date('Y-m-d', strtotime("-1 day", strtotime($date_now)));
echo $date_now;
?>

將英文文本日期時間解析為Unix 時間戳：

<?php
    echo(strtotime("now")); //現在時間
    echo(strtotime("3 October 2005")); //2015-10-03
    echo(strtotime("+5 hours")); //現在時間+5小時
    echo(strtotime("+1 week")); //現在時間+1星期
    echo(strtotime("+1 week 3 days 7 hours 5 seconds")); //現在時間 +1星期3天7小時5秒
    echo(strtotime("next Monday")); //下個星期的星期一
    echo(strtotime("last Sunday")); //上個星期的星期天
    //輸出
    //1530144600
    //1473004800
    //1530162600
    //1530749400
    //1531033805
    //1530460800
    //1529769600
?>

日期時間相減
strtotime()轉換成為Unix時間戳，可直接使用兩個時間戳相減計算時間差。

<?php
    echo $time1="2015-11-18 23:00:00";
    echo $time2="2015-11-22 05:00:00";

    echo (strtotime($time1) - strtotime($time2)); //計算相差之秒數
    echo (strtotime($time1) - strtotime($time2))/ (60); //計算相差之分鐘數
    echo (strtotime($time1) - strtotime($time2))/ (60*60); //計算相差之小時數
    echo (strtotime($time1) - strtotime($time2))/ (60*60*24); //計算相差之天數
?>

//計算相差之分鐘數

<?php
$to_time = strtotime("2017-09-12 00:00:00");
$from_time = strtotime("2017-09-12 02:00:00");
echo round(abs($to_time - $from_time) / 60,2). " minute";
?>

strtotime()轉換為日期格式date()

<?php
    //目前時間 加 1小時
    echo date('Y-m-d H:i:s', strtotime('+1 hours'));
    //2017-01-19 13:17:07
?>
