php中时间轴开发，即显示为“刚刚”、“5分钟前”、“昨天10:23”等

function tranTime($time) {            $rtime = date("m-d H:i",$time);            $htime = date("H:i",$time);                        $time = time() - $time;                    if ($time < 60) {                $str = '刚刚';            }            elseif ($time < 60 * 60) {                $min = floor($time/60);                $str = $min.'分钟前';            }            elseif ($time < 60 * 60 * 24) {                $h = floor($time/(60*60));                $str = $h.'小时前 '.$htime;            }            elseif ($time < 60 * 60 * 24 * 3) {                $d = floor($time/(60*60*24));                if($d==1)                   $str = '昨天 '.$rtime;                else                   $str = '前天 '.$rtime;            }            else {                $str = $rtime;            }            return $str;        }

函数tranTime()中的参数$time必须为Unix时间戳，如果不是请先用strtotime()将其转换成Unix时间戳。

调用函数，直接输出：

$times="1286861696 ";      echo tranTime($times);
