判断时间戳来输出刚刚/分钟前/小时前/昨天/时间 time

time.php

<?php
function T($time) {
    //获取今天凌晨的时间戳
    $day = strtotime(date('Y-m-d',time()));
    //获取昨天凌晨的时间戳
    $pday = strtotime(date('Y-m-d',strtotime('-1 day')));
    //获取现在的时间戳
    $nowtime = time();
    
    $tc = $nowtime-$time;
    if($time<$pday){
      $str = date('Y-m-d H:i:s',$time);
    }elseif($time<$day && $time>$pday){
      $str = "昨天";
    }elseif($tc>60*60){
      $str = floor($tc/(60*60))."小时前";
    }elseif($tc>60){
      $str = floor($tc/60)."分钟前";
    }else{
      $str = "刚刚";
    }
    return $str;
