[PHP]cal_days_in_month invalid date, problem z kalendarzem. Opcje

[casperii]

Panowie, spójrzcie proszę w poniższy kalendarz:
w linii:

[PHP] pobierz, plaintext 
$days_in_this_month = cal_days_in_month(CAL_GREGORIAN, $month, $year);
[PHP] pobierz, plaintext 

oraz w linii

[PHP] pobierz, plaintext 
$days_in_last_month = cal_days_in_month(CAL_GREGORIAN, $month_last, $year_last);
[PHP] pobierz, plaintext 

rzuca błędem Warning: cal_days_in_month() [function.cal-days-in-month]: invalid date. in

Problem pojawia się , gdy próbuje w kalendarzu przewinąć o kolejne 3 miesiące.

No to sprawdź sobie co pakujesz do tych funkcji, jakie wartości.

[casperii]

jak to co pakuje do tej funkcji:

[PHP] pobierz, plaintext 
 $month = 06
 
 $year = 2017 
[PHP] pobierz, plaintext 

[Pyton_000]

Taa??
to zrób

[PHP] pobierz, plaintext 
var_dump(CAL_GREGORIAN, $month, $year);
$days_in_this_month = cal_days_in_month(CAL_GREGORIAN, $month, $year);
[PHP] pobierz, plaintext 

[casperii]

Po załadowaniu kalendarza:
int(0) string(2) "06" string(4) "2017"
int(0) string(2) "07" string(4) "2017"
int(0) string(2) "08" string(4) "2017"

po kliknięciu w kolejne miesiące:
int(0) string(2) "51" string(4) "2018" // i tu się coś pierdzieli
int(0) string(2) "71" string(4) "2018"
int(0) string(2) "81" string(4) "2018"
