Req #53831 [NEW]: DateInterval constructor does not handle valid ISO 8601 strings

From: Operating system: ubuntu linux 10.10 PHP version: 5.3.5 Package: Date/time related Bug Type: Feature/Change Request Bug description:DateInterval constructor does not handle valid ISO 8601 strings Description: ------------ --- From manual page: http://www.php.net/dateinterval.construct --- The documentation says that "Each duration period is represented by an integer value followed by a period designator.", however, the ISO 8601 allows non-integer values for the last number (http://en.wikipedia.org/wiki/ISO_8601#Durations). 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 bug report at http://bugs.php.net/bug.php?id=53831&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=53831&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=53831&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=53831&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=53831&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=53831&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=53831&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=53831&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=53831&r=needscript Try newer version: http://bugs.php.net/fix.php?id=53831&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=53831&r=support Expected behavior: http://bugs.php.net/fix.php?id=53831&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=53831&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=53831&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=53831&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=53831&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=53831&r=dst IIS Stability: http://bugs.php.net/fix.php?id=53831&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=53831&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=53831&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=53831&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=53831&r=mysqlcfg
