PHP CodeBase: 将时间显示为“刚刚”“n分钟/小时前”等
在很多场合为了显示出信息的及时性,一般会将时间显示成“刚刚”,“5分钟前”,“3小时前”等,而不是直接将时间打印出来。比如微博,SNS类应用就最长用到这个功能。而一般存储在数据库中的时间格式为 Unix时间戳,所以这里记录一个将 Unix时间戳 转化为时间轴显示的PHP函数。
函数比较简单,直接看代码就很好懂了。
date_default_timezone_set('PRC');
$date = "1351836000";
echo tranTime($date);
function transfer_time($time)
{
$rtime = date("m-d H:i",$time);
$htime = date("H:i",$time);
$time = time() - $time;
if ($time
{
$str = '刚刚';
}
elseif ($time
{
$min = floor($time/60);
$str = $min.'分钟前';
}
elseif ($time
{
$h = floor($time/(60*60));
$str = $h.'小时前 '.$htime;
}
elseif ($time
{
$d = floor($time/(60*60*24));
if($d==1)
$str = '昨天 '.$rtime;
else
$str = '前天 '.$rtime;
}
else
{
$str = $rtime;
}
return $str;
}
?>
注意函数transfer_time()中的参数$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
