Req #61366 [Opn]: DateInterval should support weeks and days combined

Edit report at https://bugs.php.net/bug.php?id=61366&edit=1 ID: 61366 User updated by: evert at rooftopsolutions dot nl Reported by: evert at rooftopsolutions dot nl Summary: DateInterval should support weeks and days combined Status: Open Type: Feature/Change Request Package: Date/time related Operating System: Any PHP Version: 5.3.10 Block user comment: N Private report: N New Comment: But it appears that currently both P1W and P1D individually get parsed into the 'd' property. Wouldn't it make more sense to retain this behaviour when both are supplied, but just add them up? In a sense ->d itself is also a computed property, as this is weeks * 7 for P1W. There is no ->w property. Previous Comments: ------------------------------------------------------------------------ [2012-03-14 10:08:52] derick@php.net It should not be as part of "d", but rather as part of "days". I can quite easily add this for just weeks and days, but putting months etc in the mix is not going to work. In any case, ->days is the only computed property, the rest are as parsed. ------------------------------------------------------------------------ [2012-03-14 09:19:40] evert at rooftopsolutions dot nl Well, I have several counter points: 1) If it's not supported, it should throw an exception. At the moment it fails silently. 2) There's no reason to support a superset of ISO 8601 3) I'm using this because I'm implementing an iCalendar parser. The DURATION property type is based on ISO 8601: http://tools.ietf.org/html/rfc5545#section-3.3.6 In the wild I'm finding duration values with mixed weeks and days. Now I need to pre-parse this string, do weeks * 7, then regenerate the (almost identical) string before I can add it to the constructor. I feel adding support for W and D at the same time does not pose additional confusion, and is a sensible feature. ------------------------------------------------------------------------ [2012-03-14 01:51:40] uramihsayibok at gmail dot com ISO 8601 doesn't allow mixing weeks with anything else. If you need both then just do the math: 7 * weeks + days ------------------------------------------------------------------------ [2012-03-12 21:53:19] evert at rooftopsolutions dot nl Description: ------------ The DateInterval should support specifying weeks and days at the same time. This is documented to not be supported, but this is imho silly and confusing. Test script: --------------- <?php $di = new DateIterval('P1W1D'); echo $di->d; ?> Expected result: ---------------- 8 Actual result: -------------- 1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61366&edit=1
