Get Unix timestamp for a GMT date

설명

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

Identical to mktime() except the passed parameters represents a GMT date. gmmktime() internally uses mktime() so only times valid in derived local time can be used.

Like mktime(), arguments may be left out in order from right to left, with any omitted arguments being set to the current corresponding GMT value.

인수

hour: The hour
minute: The minute
second: The second
month: The month
day: The day
year: The year
is_dst: Parameters always represent a GMT date so is_dst doesn't influence the result.

반환값

Returns a integer Unix timestamp.

변경점

버전	설명
5.1.0	As of PHP 5.1.0, the `is_dst` parameter became deprecated. As a result, the new timezone handling features should be used instead.
