PHP Date Reference Complete PHP Date Reference

Definition and Usage

The gmmktime() function returns a Unix timestamp for a GMT date.

Syntax

gmmktime(hour,minute,second,month,day,year,is_dst)

Parameter Description
hour Optional. Specifies the hour
minute Optional. Specifies the minute
second Optional. Specifies the second
month Optional. Specifies the numerical month
day Optional. Specifies the day
year Optional. Specifies the year. The valid range for year is on some systems between 1901 and 2038. However this limitation is overcome in PHP 5
is_dst Optional. Set this parameter to 1 if the time is during daylight savings time (DST), 0 if it is not, or -1 (the default) if it is unknown. If it's unknown, PHP tries to find out itself (which may cause unexpected results). Note: This parameter became deprecated in PHP 5. The new timezone handling features should be used instead

Tips and Notes

Tip: This function is identical to mktime() except the passed parameters represents a GMT date.

Example

<?php
$my_birthday = gmmktime(0,0,0,10,3,1975);
print($my_birthday . "<br />");
print(date("M-d-Y",$my_birthday));
?>

The output of the code above would be:
