Hi guys;
What are the differences between these two code lines:
use CGI;
and use CGI qw/:standard/;
CGI.pm is a very big module with lots of methods. Normally you don't
really want to import every method into your program. If you use plain
CGI, you get almost no methods (by design). You could specifically
enumerate each method you want to import, such as:
use CGI qw{ start_html header b p h1 end_html };
Or, for convenience, you can use one of the pre-defined function sets
(which begin with a double-point) such as :standard (which will
normally import much more than you really need, so it's convenient but
not efficient). Sometimes you will use a function set but add an
oddball method or two, such as the rather common:
use CGI qw{ :standard Dump };
