前端时间做一个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,于是笔者写了次函数。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。
代码如下 | 复制代码 |
/** * 时间差计算 * * @param Timestamp $time 时间差 * @return String Time Elapsed * @author jakehu (http://www.111cn.net/) */ function time2Units ($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 ) {//大于一年显示年月日 $elapse = date('Y/m/d',time()-$time); break; } else if ( $$u > 0 ) { $elapse = $$u . $cn; break; } } return $elapse; } $past = 1390000000; //起点时间 $diff = time() - $past;//时间差 echo '发表于' . time2Units($diff) . '前'; ?> |
