在PHP和Android中将TimeStamp转换为可读时间

我将数据从服务器发送到 android并且我在数据库中有一个字段作为时间戳,我也发送数据作为 JSON但是当我发送数据时它显示如下日期：date“：1463232118”或当我删除’strtotime ‘函数从代码中显示如下日期：2016-05-18 10:24:32但是当我把’strtotime’放在一边JSON数组时,它将被发送到android端,我在浏览器中打开它显示像这样：4周前或3天前它是正确的,但当我发送它作为JSON数组时,它显示：日期“：1463232118”.这是我完整的 PHP代码指南,或者添加你知道的东西

?>

下面是我输入$curenttime = $ads [‘date’]时的输出;
????????????????????????????????$time_ago = strtotime($curenttime);
????????????????????????????????echo timeAgo($time_ago);阵列外面.

5 hours ago5 hours ago4 days ago4 days ago4 days ago

return $seconds . " seconds ago";
