php根据时间显示刚刚,几分钟前,今天,昨天的实现代码

如果大家有更好的方案欢迎交流

function diffBetweenTwoDay($pastDay){
    $timeC = time() - strtotime($pastDay);
    $dateC = round((strtotime(date('Y-m-d')) - strtotime(date('Y-m-d',strtotime($pastDay))))/60/60/24);
    if($timeC<=3*60){
        $dayC = '刚刚';
    }elseif($timeC>3*60&&$timeC<=5*60){
        $dayC = '3分钟前';
    }elseif($timeC>5*60&&$timeC<=10*60){
        $dayC = '5分钟前';
    }elseif($timeC>10*60&&$timeC<=30*60){
        $dayC = '10分钟前';
    }elseif($timeC>30*60&&$timeC<=60*60){
        $dayC = '30分钟前';
    }elseif($timeC>60*60&&$timeC<=120*60){
        $dayC = '1小时前';
    }elseif($timeC>120*60&&$dateC == 0){
        $dayC = '今天';
    }elseif($dateC == 1){
        $dayC = '昨天';
    }else{
        $dayC = date('Y-m-d',strtotime($pastDay));
    }
    return $dayC;
}
