To iterate over a hash, you want to use the keys() function.
foreach my $keys ( keys %table) {
print $table{$keys}-{search},\n;
print $table{$keys}-{shortname},\n;
}
Otherwise, perl iterates alternatively over the keys and the values of
the hash, which causes the extra newlines and the warnings.

Re: binmode with graphics, @ARGV, -T switch
In article a05101204b8710279a226@[24.70.235.44], Harvey Quamen wrote:
1) This script doesn't really translate from a jpeg to a PNG, does
it? The $image_type is simply for the header, right? I got confused
because the book says, So we will provide a high-color,
high-detail PNG if possible, or a JPEG otherwise but it seems like
the script is just dumping the data untouched right to STDOUT.
No, there's no file format conversion done by this script. It just
check if the user's browser can accept PNG files (or, in my example,
prefers them over JPEG files.) According to this user preference, the
script displays the image in the right format (but a version of the
same image must be provided in the two formats.)
2) More description: If a user calls this with
http://localhost/cgi/image_fetch.cgi/new_screenshot.png, he or she
will actually get new_screenshot.png or new_screenshot.jpeg
depending on what the browser supports. I can see that the script
is pulling the filename from $ENV{PATH_INFO} but could this data
also be retrieved from @ARGV? I tried a version with @ARGV, but it
didn't seem to work, and I wasn't sure if it was due to @ARGV or
me.
No, the @ARGV array is useless in this case since there are no
arguments passed to the script. Two ways of fetching informations from
outside the script are the CGI parameters (either with POST or GET
method), and the http server environement variables, which can be
found in the hash %ENV.
The modified version below uses CGI.pm to avoid the hassle of
remembering all the environements variables set by the http server. The
added benefit of using CGI is that it provides a path_translated
function that translates the additional path info (in our case, the
filename) into the full path in the file system.
(By the way, it would be smart to use File::Basename for this type
of thing, wouldn't it?
We could, but perl is generaly smart enough to translate '/' to '\' on
Windows, for example. And the path_translated function should probably
give back what you are expecting too.
And is that why there are extra
parentheses around the my $basename declaration? It's not in a list
context, is it?)
Yes it is! the m// operator returns true or false (1/0) if it matches,
which is handy in for example:
print matched if m/Foobar/;
If you look at the documentation (perldoc perlop), you'll read
somewhere that the m// operator:
Searches a string for a pattern match, and in scalar context
returns true if it succeeds, false if it fails.
[...]
m// in list context returns a list consisting of the
subexpressions matched by the parentheses in the pattern, i.e.,
($1, $2, $3...).
So you can see that the (\w+), if it is matched, is returned in in the
$image_path variable.
Not that if we wanted to keep track of the file extension the user
gave, we could have said for example:
my ($image_path, $image_ext) = path_translated() =~ /(\w+)\.([^.]+)$/;
3) The Camel and the Pocket Reference both say that binmode needs a
filehandle. I'm guessing the Perl in the Guelich et al book is a
slightly older version? So I should expect a few more of these
syntax differences as I go through the book? (I actually never got
this version of the script to run, even with setting up some
directories and files, but managed very well with the one in the
Camel, p. 686.)
I don't have the book right here, but in doubt, check the perldoc with
up to date information on function use. For example, to get the doc
about binmode():
$ perldoc -f binmode
4) When I test for syntax errors on the command line, I get the following:
Too late for -T option at image_fetch.cgi line 1.
I'm using Perl 5.6.0 and Apache 1.3.20 on Mac OS 10.1.

If you want to be a little more perlish, you can avoid the '\\' and put

Nafiseh Saberi wrote (in perl.beginners): hi. hope you be fine. i reply this question,also. (tables in cgi) do you know what is the difference between my answer and yours,or what is the advantages ?? Your answer is probably faster than mine in execution time since you don't have to call CGI methods to print a HTML table. However, using CGI.pm to create HTML, is in my opinion, a safeguard against HTML inconstencies. I think also makes the code more readable, as it is 100% perl and not a mix between perl and HTML. And an added bonus is that CGI.pm outputs by default (generally) valid XHTML. Of course, if you want to make really complex things in HTML, CGI.pm can be limitating. But in these case, I'll probably use a proper Templating tool (like HTML::Template, or better, Template Toolkit or HTML::Mason, all available on CPAN) I hope all of this makes sense!
