ID: 53831 Comment by: dagguh at gmail dot com Reported by: pallinger at dsd dot sztaki dot hu Summary: DateInterval constructor does not handle valid ISO 8601 strings Status: Open Type: Feature/Change Request Package: Date/time related Operating System: ubuntu linux 10.10 PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: http://en.wikipedia.org/wiki/Iso8601#Durations This decimal fraction may be specified with either a comma or a full stop, as in "P0,5Y" or "P0.5Y". Remember to accept both comma and a full stop.

This is quite important if I want to parse XML data which contains millisecond-precision durations, as the seconds will surely not be integers. Test script: --------------- <?php var_dump(new DateInterval('PT1.1S')); ?> Expected result: ---------------- Should print out a valid DateInterval object, eg.: object(DateInterval)#1 (8) { ["y"]=> int(0) ["m"]=> int(0) ["d"]=> int(0) ["h"]=> int(0) ["i"]=> int(0) ["s"]=> float(1.1) ["invert"]=> int(0) ["days"]=> bool(false) } It could also include a millisecond/microsecond/nanosecond field to accomodate additional precision. However, if the durations that are stored are still integers, it would be difficult to handle durations like "P0.5Y". Actual result: -------------- PHP Fatal error: Uncaught exception 'Exception' with message 'DateInterval::__construct(): Unknown or bad format (PT1.1S)' in -:1 Stack trace: #0 -(1): DateInterval->__construct('PT1.1S') #1 {main} thrown in - on line 1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=53831&edit=1
