Description:
------------
$date = DateTime::createFromFormat('d M Y A h:i', '11 Mar 2013 PM 3:34');
Returns:   [12] => Unexpected data found.

Works only in this case:
$date = DateTime::createFromFormat('d M Y h:i A', '11 Mar 2013 3:34 PM');


Test script:
---------------
$date = DateTime::createFromFormat('d M Y A h:i', '11 Mar 2013 PM 3:34');
if(!$date) echo 'Doesn\'t work =(';

Expected result:
----------------
Returns DateTime object

Actual result:
--------------
False
(Unexpected data found.)

This behaviour is not in itself a bug.

The issue is that the wrong error is reported, and the root cause of this is actually a bug in the way date_get_last_errors() works rather than the date parsing mechanism.

As fixing this would be a BC break, I have submitted a patch that ensures that in this specific case the correct error is reported.

If the behaviour is "not a bug" then documentation should also be updated to mention that AM/PM will not be parsed until after an hour is parsed.

I fail to see why this limitation is in any way necessary; some explanation would be helpful!

The fix for this bug has been committed.
If you are still experiencing this bug, try to check out latest source from https://github.com/php/php-src and re-test.
Thank you for the report, and for helping us make PHP better.

This is fixed for PHP 8.0(.10) and later, where it now correctly shows the error message:

<?php
$date = DateTime::createFromFormat('d M Y A h:i', '11 Mar 2013 PM 3:34');
var_dump(DateTime::getLastErrors());
?>

array(4) {
  ["warning_count"]=>
  int(0)
  ["warnings"]=>
  array(0) {
  }
  ["error_count"]=>
  int(1)
  ["errors"]=>
  array(1) {
    [12]=>
    string(51) "Meridian can only come after an hour has been found"
  }
}
