PHP DateTime无法从历元时间戳分析时间字符串

Question

我正试图以小时为单位显示自这样一个日期以来的数字。。。

$timestamp1 = '1517158402';
$timestamp2 = '1530204802';
$timestamp3 = '1548694384';

if ($timestamp1 && $timestamp2 && $timestamp3 ) {

    /* Calculate time */
    $timestamp1_obj = new DateTime($timestamp1);
    $timestamp2_obj = new DateTime($timestamp2);
    $timestamp3_obj = new DateTime($timestamp3);

    $since_start = $timestamp2_obj->diff($timestamp3_obj);
    echo $since_start->h.' hours';

}

这是给我的错误信息。。。

Uncaught Exception: DateTime::__construct(): Failed to parse time string

有人知道我哪里出错了吗？

Answer 1

您需要使用setTimestamp。

$date = new DateTime();
$date->setTimestamp(1171502725);
