PHP中"多少时间之前的"做法

经常看到,有的视频站上,都显示某个视频,是多少天之前,多少分钟之前,多少年之前,

其实实现起来不麻烦,下面是函数:

<?PHP

include_once('timeago.php');

$cur_time1 ="1291684422";//UNIX时间,统一用

echo time_ago($cur_time1) ;

?>

timeago.php

<?PHP

function time_ago($cur_time){

$time_ = time() - $cur_time;

$seconds =$time_;

$minutes = round($time_ / 60);

$hours = round($time_ / 3600);

$days = round($time_ / 86400);

$weeks = round($time_ / 604800);

$months = round($time_ / 2419200);

$years = round($time_ / 29030400);

//Seconds

if($seconds <= 60){

$time="$seconds seconds ago";

//Minutes

}else if($minutes <= 60){

if($minutes == 1){

$time="one minute ago";

}else{

$time="$minutes minutes ago";

}

//Hours

}else if($hours <= 24){

if($hours == 1){

$time="one hour ago";

}else{

$time="$hours hours ago";

}

//Days

}else if($days <= 7){

if($days == 1){

$time="one day ago";

}else{

$time="$days days ago";

}

//Weeks

}else if($weeks <= 4){

if($weeks == 1){

$time="one week ago";

}else{

$time="$weeks weeks ago";

}

//Months

}else if($months <= 12){

if($months == 1){

$time="one month ago";

}else{

$time="$months months ago";

}

//Years

}else{

if($year == 1){

$time="one year ago";

}else{

$time="$year years ago";

}

}

return $time;

}

?>

注意,由于英文跟中文的语法的习惯,中文的话,1年和2年是没复数的表示上的分别的,所以上面的代码自己适当改下就可以用了
