Edit report at http://bugs.php.net/bug.php?id=54402&edit=1 ID: 54402 User updated by: tom dot haws at gmail dot com Reported by: tom dot haws at gmail dot com Summary: Format string not documented correctly for %I minutes and $S seconds Status: Bogus Type: Documentation Problem Package: Documentation problem Operating System: Ubuntu PHP Version: 5.3SVN-2011-03-27 (snap) Block user comment: N Private report: N New Comment: The statement at http://www.php.net/datetime.format#Parameters that the format string for the time diff is a "format accepted by date()" needs to be replaced with a link to the correct page http://www.php.net/manual/en/dateinterval.format.php Previous Comments: ------------------------------------------------------------------------ [2011-04-26 22:12:39] salathe@php.net The DateTime::diff() method returns a DateInterval object, whose format() method you then call. The format characters are listed on the page for DateInterval::format() [1] which are different to the format characters available for date() and DateTime::format(). [1] http://www.php.net/manual/en/dateinterval.format.php ------------------------------------------------------------------------ [2011-03-27 18:29:19] tom dot haws at gmail dot com The case is worse than I stated. I was not precise about the results vs. expected. Following the documentation strictly gives the following result: // Result: Y-m-d H:i:s // Expected: 25-02-25 04:00:00 from the documented format string. ------------------------------------------------------------------------ [2011-03-27 18:25:10] tom dot haws at gmail dot com Description: ------------ --- From manual page: http://www.php.net/datetime.format#Parameters --- Note about the time diff format string: As far as I can tell, the datetime diff format string I ended up using is not documented anywere. The PHP manual says that the format string for the time diff is a "format accepted by date()". That would look like 'Y-m-d H:i:s', but that did not work. The other documented format I could find is the one accepted by strftime. That would look like '%Y-%M-%D %H:%i:%s', but that did not give leading zeroes for minutes and seconds. $my_birth_tz=new DateTimeZone('America/Phoenix'); $my_birth=new DateTime('1956-09-19 08:38:00',$my_birth_tz); $my_marriage_tz=new DateTimeZone('America/Los_Angeles'); $my_marriage=new DateTime('1981-12-14 11:38:00', $my_marriage_tz); $my_marriage_age=$my_marriage->diff($my_birth); echo $my_marriage_age->;format('%Y-%M-%D %H:%I:%S'); // Result: 25-02-25 04:00:00 Test script: --------------- $my_birth_tz=new DateTimeZone('America/Phoenix'); $my_birth=new DateTime('1956-09-19 08:38:00',$my_birth_tz); $my_marriage_tz=new DateTimeZone('America/Los_Angeles'); $my_marriage=new DateTime('1981-12-14 11:38:00', $my_marriage_tz); $my_marriage_age=$my_marriage->diff($my_birth); echo $my_marriage_age->;format('%Y-%M-%D %H:%I:%S'); // Result: 25-02-25 04:00:00 // Note the non-documented format() string. echo $my_marriage_age->;format('%Y-%M-%D %H:%i:%s'); // Result: 25-02-25 04:0:0 // Expected 25-02-25 04:00:00 from the documented format string. Expected result: ---------------- // Expected 25-02-25 04:00:00 from the documented format string. I wanted leading zeros. Actual result: -------------- // Result: 25-02-25 04:0:0 No leading zeros. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54402&edit=1
