Question

I have a php script which includes the date() function. But somehow it messes the day names up.

the line is as simple as

date ("l",mktime(0,0,0,$test3,$test2,$test4));

When I test it with a current date e.g.

date ("l",mktime(0,0,0,11,07,2011));

it returns the correct day, Monday. But if I go just one day further

date ("l",mktime(0,0,0,12,07,2011));

it returns Wednesday..

Do you have any idea where the problem might be? Anything with timezone or so..? I’ve never used the date function before and couldn’t find any solution googeling it or in here..

I appreciate any answer! thx in advance!

Answer 1

The fourth parameter of mktime() is the month. November 7, 2011 is a Monday, but December 7, 2011 is a Wednesday.

int mktime (
    [ int $hour = date("H") 
    [, int $minute = date("i") 
    [, int $second = date("s") 
    [, int $month = date("n") 
    [, int $day = date("j") 
    [, int $year = date("Y") 
    [, int $is_dst = -1 ]
    ]]]]]] )

Additionally, you should remove leading zeros where present ( 07 => 7 ) to avoid unexpected errors.
