Two ways to calculate the difference between two timestamps in PHP-PHP Tutorial-php.cn

Timestamp (timestamp), usually a sequence of characters, uniquely identifies a certain moment in time. Digital timestamp technology is a variant of digital signature technology. Time is also a very important requirement in PHP. In this article, we mainly talk about two methods for PHP to calculate the day, hour, minute and second difference between two timestamps.

First type:

/** * 计算两个时间戳之间相差的日时分秒 * @param $unixTime_1 开始时间戳 * @param $unixTime_2 结束时间戳 * @return array */ function timeDiff($unixTime_1, $unixTime_2) { $timediff = abs($unixTime_2 - $unixTime_1); //计算天数 $days = intval($timediff / 86400); //计算小时数 $remain = $timediff % 86400; $hours = intval($remain / 3600); //计算分钟数 $remain = $remain % 3600; $mins = intval($remain / 60); //计算秒数 $secs = $remain % 60; return ['day' => $days, 'hour' => $hours, 'min' => $mins, 'sec' => $secs]; } //Array ( // [day] => 1 // [hour] => 0 // [min] => 3 // [sec] => 31 //)
