date - 我如何转换 yyyy-MM-ddThh :mm:sszzz to timestamp with php?

Question

我试过这段代码:

$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;

但给了我这个错误:

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

这段代码有什么问题？

strtotime() 应该能够很好地解析并返回 Unix 时间戳。

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

echo $timestamp;  // prints: 1340374015
