Re: getting a string result from Date

Hi Lorenzo please give the code a try, i was baffled to find the second $currdate assignment doesn't work when it's fed back into the argument of the Date object in the next iteration of the loop. using $currDate = $date->format('%Y-%m-%d'); C:\htdocs\test>php dateTest.php string(10) "2004-04-01" string(10) "2004-03-25" string(10) "2004-03-18" string(10) "2004-03-11" string(10) "2004-03-04" using $currDate = "{$date->year}-{$date->month}-{$date->day}"; C:\htdocs\test>php dateTest.php string(8) "2004-4-1" string(8) "2004-4-1" string(8) "2004-4-1" string(8) "2004-4-1" string(8) "2004-4-1"

the second one works, but you don't have the date returned in the ISO-8601 format because the numbers are not 0-padded.

my tests show passing ISO or non-ISO formatted dates as args to the Date object make no difference - both work. this bug took me ages to find because the malfunctioning is unexpected (i can post the code again if needed). cheers Demian Lorenzo Alberton wrote:

However I have come across one hitch which I've solved but don't understand the solution. Does any understand why the first method of assigning the results of a date span operation to a string works and not the (commented) second? $currDate = $date->format('%Y-%m-%d'); #$currDate = "{$date->year}-{$date->month}-{$date->day}";

the second one works, but you don't have the date returned in the ISO-8601 format because the numbers are not 0-padded. For instance, you get "2004-4-1" instead of "2004-04-01". You should do something like $currDate = sprintf("%04d-%02d%02d", $date->year, $date->month, $date->day); but of course $currDate = $date->format('%Y-%m-%d'); is much shorter and clearer :-) HTH Lorenzo
