PHP Bug Type: Date/time related
Bug description: DateInterval:createDateFromString() silently fails
Description:
------------
Documentation of DateInterval:createDateFromString() does not state what
happens when the function fails. So far as I can tell, it seems to produce
an empty DateInterval object.
If an empty object is the expected behaviour then it should be documented.
And more importantly, there should be an easy way to test if the object is
empty.
Given that creating a DatePeriod using an empty DateInterval consumes all
the memory available to a session, it seems to me that allowing empty
DateIntervals is a design flaw.
Reproduce code:
---------------
---
>From manual page: dateinterval.createfromdatestring#Return Values
---
$i=DateInterval::createFromDateString('P1D');//expected to fail
$d1=date_create('2009-10-27');
$d2=date_create('2009-11-15');
$p=new DatePeriod($d1,$i,$d2); //PHP times out
Expected result:
----------------
expect error at line $i=DateInterval::createFromDateString('P1D')
Actual result:
--------------
Fatal error: Allowed memory size of 314572800 bytes exhausted (tried to
allocate 72 bytes)
