使用正则表达式将日期/时间字符串更改为PHP中的时间戳
I'm struggling with a RegEx to change a date/time string to a timestamp. The format of the string is 'd/m/Y \a\t g:ia'
(e.g. 15/06/2012 at 6:00pm).
I need to do this to ensure that a date is not in the past.
I can do the date part (just 'd/m/Y'
) using the following code, but it's the rest that I am struggling with. Thanks.
$expires = preg_replace("/(\d{2})\/(\d{2})\/(\d{4})/", "\\3-\\2-\\1" , $poll['poll_expired']);
Thanks.

Why can't you do something like this?
$date = DateTime::createFromFormat('d/m/Y \a\t g:ia', ' 15/06/2012 at 6:00pm');
$expires = $date->format('U');
(Not tested but you get the idea.)
