如何将yyyy-MM-ddThh：mm：sszzz转换为带有PHP的时间戳？

Question

I have tried this code:

$dateFromDB = '2012-06-22T14:06:55+00:00';

$newDate = DateTime::createFromFormat('yyyy-MM-ddThh:mm:sszzz', $dateFromDB);
$date = $newDate->format('U'); // convert to timestamp

echo $date;

but gave me this error:

Fatal error: Call to a member function format() on a non-object in...

What is the problem with this code?

Answer 1

strtotime() should be able to parse that nicely and returns Unix timestamp.

<?php
$timestamp = strtotime('2012-06-22T14:06:55+00:00');

echo $timestamp;  // prints: 1340374015
