问题
I want to convert a date by the following statement
$date=date('d M Y, H:m',strtotime($date));
It printed out 09 Sep 2012, 11:09 when I tried various values of $date:
11:00 AM Sunday, 09 Sep 2012
Sunday 09 Sep 2012, 11:00 AM
09 Sep 2012 11:00 AM
What date format does the strtotime() function need? It seems to me at least one of them meets the "English textual datetime description" condition.

Valid formats for strtotime are detailed here.

From this site (http://www.tuxradar.com/practicalphp/4/5/2)
Be wary of dates such as this one: August 25, 2003, 10:26am. Although this may look perfectly well-formed, strtotime() is not able to handle it because it has commas in there - yes, they make it much more readable for us, but strtotime() gets confused handling them. If you have dates with commas in, be sure to strip them out using str_replace().

Looks like the only way to go is to sort the elements in proper order by regular expressions and then replace the month name by corresponding number. Such a string strtotime will manage. Note: I'm talking about PHP 5.2x
EDIT: I found the reason, why strtotime "wasn't working" was that I made a typo in the date formating string, there should be 'd M Y, H:i'
