Hashes in Perl (part 1)
Define a hash (associative array):
my %hash = ("key" => "value", currentlyPlaying => "Trans Am",
"is_$someScalar" => 1);
Determine the number of elements in a hash (works on arrays too), similar to a .length() or UBound - use the scalar function:
my $hashLength = scalar %hash;
my $arrLength = scalar(@array); # this would work too
To quickly print out the contents of a hash, use keys:
print "Content-type:text/html\n\n";
foreach $k (keys %vars) { print "$k => ".$vars{$k}; }
That's it for now.
