This is converting it to a unix timestamp: strtotime($datetime), but you're converting it back to a date again with date().
这是将其转换为 unix timestamp: strtotime($datetime)，但您再次将其转换回日期date().

To extend the answers here with an object-oriented solution, the DateTime class must be named. The DateTime class is available since PHP 5.2 and can be used as follows.
要使用面向对象的解决方案扩展此处的答案，必须命名 DateTime 类。DateTime 类从 PHP 5.2 开始可用，可以按如下方式使用。
$date = DateTime::createFromFormat('Y-m-d H:i:s', '2012-07-25 14:35:08');
echo $date->getTimestamp(); // output: 1343219708
Or even as a one-liner
甚至作为单线
echo $date = (new DateTime('2012-07-25 14:35:08'))->getTimestamp();
// output: 1343219708
