Facebook 样式的时间戳
Facebook (x mins age, y hours ago etc) function nicetime($date) { if(empty($date)) { return "No date provided"; } $periods = array("second", "minute", "hour", "day", "week", "month", "year", "decade"); $lengths = array("60","60","24","7","4.35","12","10"); $now = time(); $unix_date = strtotime($date); // check validity of date if(empty($unix_date)) { return "Bad date"; } // is it future date or past date if($now > $unix_date) { $difference = $now - $unix_date; $tense = "ago"; } else { $difference = $unix_date - $now; $tense = "from now"; } for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) { $difference /= $lengths[$j]; } $difference = round($difference); if($difference != 1) { $periods[$j].= "s"; } return "$difference $periods[$j] {$tense}"; }
语法:
<?php $date = "2015-07-05 03:45"; $result = nicetime($date); // 2 days ago ?>
