Example
Example of both strftime() and gmstrftime():
<?php echo(strftime("%b %d %Y %X", mktime(20,0,0,12,31,98))."<br />"); echo(gmstrftime("%b %d %Y %X", mktime(20,0,0,12,31,98))."<br />"); //Print the current date, time, and time zone. echo(gmstrftime("It is %a on %b %d, %Y, %X time zone: %Z",time())); ?> |
The output of the code above could be:
Dec 31 1998 20:00:00 Dec 31 1998 19:00:00 It is Wed on Jan 25, 2006, 11:32:10 time zone: W. Europe Standard Time |
