Question

如何使$your_date = strtotime("2010-01-01")成为动态的?我是说(2010-01-01)一个(动态的)?

代码如下:

 $started = get_post_meta(get_the_ID(), 'wtf_started', true);
 $now = time(); // or your date as well
 $your_date = strtotime("$started");
 $datediff = $now - $your_date;
 echo floor($datediff/(60*60*24));

Answer 1

直接传递变量，不加引号。

$your_date = strtotime($started);

即使你的代码也工作得很好但是试着去掉引号

Answer 2

试试这个

$startdate = new DateTime(date("Y-m-d", strtotime(get_post_meta(get_the_ID(), 'wtf_started', true))));
$now = new DateTime("now");
$datediff = date_diff($startdate,$now);
echo $datediff->format('%d days');
