spliting (CGI)

could someone tell me what this line means?

$year = (split /:/)[3];

I know
$year = (split /:/); and
$year = (split /:/,$_);
is the same but what is [3] doing there?

Thx...

Why not try it and find out for free.  Not too difficult to do, and
certainly quicker than waiting for a sarcastic answer.

Hmmm.  I've never seen that notation before, offhand.  But it's obvious to
me what it does.  It populates $year with the third element of the
resultant array generated by split().

As for the book you got, it's obviously not helping.  Or you're not reading
it.  If you want a good perl book that's comprehensive, I told you, get the
O'Reilley copy of "Programming Perl".  www.oreilley.com/catalog/pperl3/

As for perl web sites...try starting at www.perl.org.  :)

And as for CGI...God, when I learned CGI it was 1994, and I was using
resources off of http://hoohoo.ncsa.uiuc.edu from the Forms Tutorial, along
with demo C source from the NCSA httpd server that predated Apache.

When I learned CGI in perl, I first started with cgi-lib.pl originally, and
then I moved to CGI.pm.  The latter is the way to go, definitely.
`perldoc CGI` and start reading.

And as for perldoc, check in your \perl\bin\ directory.  And yes (sort of),
'man' is generally a unix command.  It's hardly linux-specific.  Hell, you
can have man for windows if you install cygwin.  :)  As it is, you can get
all the man pages out of perldoc, since they're all created from the POD
anyway.  `perldoc perl`  I just use `man` for the main pages because it's
less typing and I'm used to that command for all other unix docs.
