PHP把时间转换成几分钟前、几小时前、几天前的几个函数、类

时间:2017-08-11 16:57点击:
这篇文章主要介绍了php计算时间几分钟前、几小时前、几天前的几个函数、类分享,需要的朋友可以参考下
一、函数实现

实例:


    <?php  
    header("Content-type: text/html; charset=utf8");  
    date_default_timezone_set("Asia/Shanghai");   //设置时区  
    function time_tran($the_time) {  
        $now_time = date("Y-m-d H:i:s", time());  
        //echo $now_time;  
        $now_time = strtotime($now_time);  
        $show_time = strtotime($the_time);  
        $dur = $now_time - $show_time;  
        if ($dur < 0) {  
            return $the_time;  
        } else {  
            if ($dur < 60) {  
                return $dur . '秒前';  
            } else {  
                if ($dur < 3600) {  
                    return floor($dur / 60) . '分钟前';  
                } else {  
                    if ($dur < 86400) {  
                        return floor($dur / 3600) . '小时前';  
                    } else {  
                        if ($dur < 259200) {//3天内  
                            return floor($dur / 86400) . '天前';  
                        } else {  
                            return $the_time;  
                        }  
                    }  
                }  
            }  
        }  
    }  
      
      
    echo time_tran("2014-7-8 19:22:01");  
    ?>  


实例2:


    <?php  
    function time_tranx($the_time){  
       $now_time = date("Y-m-d H:i:s",time()+8*60*60);  
       $now_time = strtotime($now_time);  
       $show_time = strtotime($the_time);  
       $dur = $now_time - $show_time;  
       if($dur < 0){  
            return $the_time;  
       }else{  
            if($dur < 60){  
             return $dur.'秒前';  
            }else{  
                 if($dur < 3600){  
                  return floor($dur/60).'分钟前';  
                 }else{  
                      if($dur < 86400){  
                         return floor($dur/3600).'小时前';  
                      }else{  
                           if($dur < 259200){ //3天内  
                                return floor($dur/86400).'天前';  
                           }else{  
                                return $the_time;  
                           }  
                      }  
                }  
            }  
       }  
    }  
    echo time_tranx("2014-7-8 19:22:01");  
    ?>  


实例3:

            '86400'=>'天',  
            '3600'=>'小时',  
            '60'=>'分钟',  
            '1'=>'秒'  
        );  
        foreach ($f as $k=>$v)    {  
            if (0 !=$c=floor($t/(int)$k)) {  
                return $c.$v.'前';  
            }  
        }  
    }  
    echo format_date("1404600000");  
    ?>

        $str = '';  
        $timer = strtotime($date);  
        $diff = $_SERVER['REQUEST_TIME'] - $timer;  
        $day = floor($diff / 86400);  
        $free = $diff % 86400;  
        if($day > 0) {  
            return $day."天前";  
        }else{  
            if($free>0){  
                $hour = floor($free / 3600);  
                $free = $free % 3600;  
                    if($hour>0){  
                        return $hour."小时前";  
                    }else{

                            $min = floor($free / 60);  
                            $free = $free % 60;  
                            if($min>0){

                            }else{

                                }  
                           }
