日期差异

Question

我在mysql表中有两个日期。

sample:
date1: 2011-01-01 06:40:00
date2: 2011-02-19 18:00:00

我需要返回它们之间的区别，如下所示：

50天，12小时，20分钟

我如何在PHP或MYSQL中执行此操作？

Answer 1

此代码应该满足您的需求：

<?php
$result = mysql_query("SELECT (date1, date2) FROM myTable;");
while (list($date1, $date2) = mysql_fetch_array($result)) {
    $firstdate = new DateTime($date1);
    $seconddate = new DateTime($date2);
    $diff = $firstdate->diff($seconddate);
    echo $diff->d . " days, " . $diff->h . " hours, " . $diff->i . "minutes\n";
}
?>

Answer 2

试试这个，

SELECT CONCAT(
FLOOR(TIMESTAMPDIFF(HOUR,'2011-01-01 06:40:00', '2011-02-19 18:00:00')  / 24), ' days ',
MOD(TIMESTAMPDIFF(HOUR,'2011-01-01 06:40:00', '2011-02-19 18:00:00'), 24), ' hours ',
MINUTE(TIMESTAMPDIFF(second,'2011-01-01 06:40:00', '2011-02-19 18:00:00')), ' minutes')
