#50020 [Fbk->Opn]: DateInterval:createDateFromString() silently fails

ID: 50020 User updated by: jennifer dot kimball at nrc dot ca Reported By: jennifer dot kimball at nrc dot ca -Status: Feedback +Status: Open Bug Type: Date/time related Operating System: Solaris 10 PHP Version: 5.3.0 New Comment: The snapshot fixes the memory problem for me. But there is still no way to easily tell if a DateInterval size is zero or if there were errors creating the DateInterval.

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) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50020&edit=1
