前段时间做一个APP后台时用户要求用户的评论以xx分钟前这种格式显示,给用户以良好的体验,于是笔者写了一个函数,本函数主要是利用PHP计算两个时间之间的差值,通过差值来转换,虽然代码很简单,但是很实用.PHP实例代码如下:
- <?php
-
-
-
-
-
-
-
- function time2Units ($time)
- {
- $year = floor($time / 60 / 60 / 24 / 365);
- $time -= $year * 60 * 60 * 24 * 365;
- $month = floor($time / 60 / 60 / 24 / 30);
- $time -= $month * 60 * 60 * 24 * 30;
- $week = floor($time / 60 / 60 / 24 / 7);
- $time -= $week * 60 * 60 * 24 * 7;
- $day = floor($time / 60 / 60 / 24);
- $time -= $day * 60 * 60 * 24;
- $hour = floor($time / 60 / 60);
- $time -= $hour * 60 * 60;
- $minute = floor($time / 60);
- $time -= $minute * 60;
- $second = $time;
- $elapse = '';
-
- $unitArr = array('年前' =>'year', '个月前'=>'month', '周前'=>'week', '天前'=>'day',
- '小时前'=>'hour', '分钟前'=>'minute', '秒前'=>'second'
- );
-
- foreach ( $unitArr as $cn => $u )
- {
- if ( $year > 0 ) {
- $elapse = date('Y/m/d',time()-$time);
- break;
- }
- else if ( $$u > 0 )
- {
- $elapse = $$u . $cn;
- break;
- }
- }
-
- return $elapse;
- }
-
- $past = 1390000000;
- $diff = time() - $past;
-
- echo '发表于' . time2Units($diff) . '前';
- ?>
