PHP日期时间为Unix时间戳

Question

How can I convert string "M-d-Y::H:i:s" to unix timestamp in php. I just realized manipulating date and time must be the most time consuming entity in any programming language.

Trivial Question: Why do you think there isn't any universal date time format. Why are there so many variations of same data? AArrhh.

Answer 1

The OOP way (requires PHP >= 5.3.0):

$dt = DateTime::createFromFormat("M-d-Y::H:i:s", $input);
$ts = $dt->getTimestamp();

You should of course check the return value of createFromFormat (it's false if an error occurs) but you should also definitely check DateTime::getLastErrors(); otherwise you might be surprised if e.g. your input has a day of "Jan 32". See my answer here for more info.
