本文实例讲述了php返回相对时间（如：20分钟前，3天前）的方法。分享给大家供大家参考。具体如下：
function plural($num) { if ($num != 1) return s;}function getrelativetime($date) { $diff = time() - strtotime($date); if ($diff<60) return $diff. 秒.plural($diff). 前; $diff = round($diff/60); if ($diff<60) return $diff. 分钟.plural($diff). 前; $diff = round($diff/60); if ($diff<24) return $diff. 小时.plural($diff). 前; $diff = round($diff/24); if ($diff<7) return $diff. 天.plural($diff). 前; $diff = round($diff/7); if ($diff<4) return $diff. 星期.plural($diff). 前; return on .date(f j, y, strtotime($date));}
希望本文所述对大家的php程序设计有所帮助。
