wordpress - What's the right format to create a PHP DateTime instance of '2016.04.30 PM 7:30' via DateTime::createFromFormat? -

i'm working on wordpress project should custom post metadata, convert datetime instance, , math it.

when echo get_post_meta, looks follows.

2016.04.30 pm 7:30

the format i'm using datetime instance follows.

y.m.d g:i

but return value of datetime::createfromformat false.

// 2016.04.30 pm 7:30 $start_at = datetime::createfromformat( 'y.m.d g:i', get_post_meta(get_the_id(), 'as_date', true)); if ($start_at === false) {     echo 'false format: ' . get_post_meta(get_the_id(), 'as_date', true); } else {     echo $start_at->gettimestamp(); } 

the result false format: 2016.04.30 pm 7:30.

what missing here? think must trivial can't through.

testing, found problem character in format 'a'. poked around , found bug in php (that apparently not bug @ all!)

going through source code, looks not parse , pm until after hour has been parsed.

probably best bet quick pass through regular expression move am/pm end:

$thedate = get_post_meta(get_the_id(), 'as_date', true); $thedate = preg_replace("/([0-9.]+) ([ap]m) ([0-9:]+)/i", "$1 $3 $2", $thedate); $start_at = datetime::createfromformat('y.m.d g:i a', $thedate);
