In addition to Matthew's response...
Strtotime() and mktime() both return a serial date. That's the
"1101945775" number you got. To get this back to a YYYYmmdd format that
you seem to be trying to do with mktime(), you want to use date() as
Matthew suggested. Again, I think examples help more than "RTFM":
date("Ymd",strtotime("now"));
mktime() and strtotime() produce the same output which is not a
human-readable date format. So basically, in your example below, you
told it that you wanted:
The serial date (mktime()) of hour "Ymd" (evaluates as 0 I believe),
minute "1101945775", with seconds, month, day and year all empty. I
think the leaving them empty is ok since they're optional from right to
left, and the excessive number of minutes probably wouldn't be a big
deal (unless it goes past the maximum date rate, which looks like what
it's doing). Let's do a quick calc:
Looks like the max number that mktime() can produce is:
2147483647
This is 1/18/2038 22:14:07
If you take your serial date "1101945775" and pipe it into the minutes
section of mktime(), it'll produce that number times 60 (60 seconds in a
minute) and try to get that date. This produces a number:
66116746500
Significantly bigger than the max serial date for Windows mentioned
above.
Long answer to maybe help you understand how it all works.
Btw: The serial date is the number of seconds since the beginning of the
"Unix Epoch" (# of secs since January 1, 1970 that is... Hey, time's
gotta start somewhere eh?)
Hope this helps clarify mktime(), strtotime() and date().
