Edit report at https://bugs.php.net/bug.php?id=53634&edit=1 ID: 53634 Updated by: stas@php.net Reported by: danielc at analysisandsolutions dot com Summary: unknown property when writing to DateInterval::$days -Status: Assigned +Status: Closed Type: Bug Package: Date/time related Operating System: linux PHP Version: 5.3SVN-2010-12-30 (SVN) Assigned To: stas Block user comment: N Private report: N New Comment: The fix for this bug has been committed.

For Windows: http://windows.php.net/snapshots/ Thank you for the report, and for helping us make PHP better. $days is not writable by design of DateInterval since it's a derived property. So not being able to write it is not a bug. If additional functionality is needed, please create FR or RFC describing how it should work. Previous Comments: ------------------------------------------------------------------------ [2011-01-30 13:59:58] danielc at analysisandsolutions dot com Why should days be read only? All other properties are writable. Days needs to be writable too. Writing to various properties is necessary when overloading the date classes (to compensate for bugs, etc). ------------------------------------------------------------------------ [2011-01-30 11:57:20] stas@php.net Hmm... Actually you're not supposed to be writing to days property, it should be read only. I'll fix it. ------------------------------------------------------------------------ [2011-01-24 18:39:45] danielc at analysisandsolutions dot com While the recent commit removes the fatal error, the property can not be written to. Here is the output of the initial test script (above) as of svn revision 307713: S: 8 DAYS: -99999 DAYS: -99999 ------------------------------------------------------------------------ [2011-01-24 03:49:50] stas@php.net This bug has been fixed in SVN.

It is readable. All other properties of DateInterval shown in var_dump() are writeable. While similar to Bug #52738, this involves an actual property of the DateInterval class. Test script: --------------- $i = new DateInterval('P1D'); $i->s = 8; echo "S: $i->s\n"; echo "DAYS: $i->days\n"; $i->days = 6; echo "DAYS: $i->days\n"; Expected result: ---------------- S: 8 DAYS: -99999 DAYS: 6 Actual result: -------------- S: 8 DAYS: -99999 PHP Fatal error: main(): Unknown property (days) in /home/danielc/test.php on line 7 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=53634&edit=1
