How do I convert an ISO8601 date to another format in PHP?

问题

Facebook outputs dates in ISO8601 format - e.g.: 2011-09-02T18:00:00

Using PHP, how can I reformat into something like: Friday, September 2nd 2011 at 6:00pm

Nb - I was doing it in Javascript, but IE has date bugs so I want a cross-browser solution.

回答1:

A fast but sometimes-unreliable solution:

$date = '2011-09-02T18:00:00';

$time = strtotime($date);

$fixed = date('l, F jS Y \a\t g:ia', $time); // 'a' and 't' are escaped as they are a format char.

Format characters detailed here.

Converting from ISO 8601 to unixtimestamp :

strtotime('2012-01-18T11:45:00+01:00');
// Output : 1326883500

---

Converting from unixtimestamp to ISO 8601 (timezone server) :

date_format(date_timestamp_set(new DateTime(), 1326883500), 'c');
// Output : 2012-01-18T11:45:00+01:00

---

Converting from unixtimestamp to ISO 8601 (GMT) :

date_format(date_create('@'. 1326883500), 'c') . "\n";
// Output : 2012-01-18T10:45:00+00:00

---

Converting from unixtimestamp to ISO 8601 (custom timezone) :

date_format(date_timestamp_set(new DateTime(), 1326883500)->setTimezone(new DateTimeZone('America/New_York')), 'c');
// Output : 2012-01-18T05:45:00-05:00
