Subject: really dumb question about arrays
Message-Id: <36D1EBB4.97E90057@provence-shop.com>
Hi,
I have an asociative array that is made like this (or at least, it
should be!): name1::value1&name2::value2&...&namen::valuen.
But when I transfer the content of %myhash into @myarray by typing :
@myarray = %myhash to split the name / value pairs, my array looks like
this: name1 value1 name2 value2 ... namen valuen.
any idea why this is like this, or anything I am doing wrong???
I tried @myarray eq %myhash but @myarray is now empty.
Oh, two last things:
1- I am completely new to PERl, i mean that i am slowly discovering
this!
2- I am using matt Wright's cookie.lib to retrieve compressed cookies,
hence the & :: type of separation.
Thank you for your help nd time.

Perl is doing what it does best - making some sort of sense of your code
(and in this case creating a list out of your hash). What I suspect you
wanted was an array consisting of all the values in your hash: this can be
achieved very easily by
@myarray = values %myhash;
Incidentally, a similar array of key values can be created by
@mykeyarray = keys %myhash;

It's doing what you asked it to do, what do you want it to do ??
You can use the values command to get just a list of values (keys for
keys). Please explain clearly what you want and you will either help
yourself or enable a c.l.p.m contributor to help you.

Subject: Re: Redirecting to a password protected page
Message-Id: <36D32E2C.399092EF@wfubmc.edu>
I've been trying to work out something like this for a while. I originally
had the user login, check to see if the password is OK via Perl, then
redirect them to the password protected page by using an url in this
format:
username:password@yoursite.com/protected/here
This actually works with .htaccess if you type it in the browser, BUT, in a
cgi script it works fine with Netscape but in IE4 it prompts the user for
the .htaccess password - what we don't want.
THERE IS ANOTHER WAY AROUND THIS, that I though of, but haven't tried yet,
and that is to redirect the user to a page that has a "meta - refresh" tag
were they are forwarded to username:password@yoursite.com/protected/here.
Might work smoothly in both browsers. If you figure out a way to do this,
let me know!
Would be great because then you can monitor access to your site via the cgi
script logins rather than have to monitor your server log file.

No, the guy wants to know how he can do that from a CGI script. There
is no specific relevance to perl.

I am familier with the solutions you suggested, the problem with them is
that they expose the password to the end user.
I don't want him to see the login&password I am using.

Message-Id: <36D5554D.FCF6BB7D@joe10.com>
Hi there,
use(ing) CGI:
I'm trying to keep some CGI scripts secure and free from unwanted use or
input.
Is it legit to have your main body only execute if referer() returns the page
(or from each of an array) I think the script should be allowed to be called
from? Would this be relatively secure?
TIA, Joe

HTTP_REFERER is trivally spoofed. it is not in any way secure.

This seems to be the best of the regular expressions offered, except
for the bug. (The dollar sign is missing.)
/^\$\d{1,3}(?:,\d\d\d)*\.\d\d$/
To match dollar amounts like "$.02", I suppose you just make
everything between the dollar sign and the decimal point optional.
Right?
/^\$(?:\d{1,3}(?:,\d\d\d)*)?\.\d\d$/
Look, Ma! No alternation!

Why not replacing the pattern with
m/<(.*?@.*?)>/
It will put to $1 the text inside <>
Or just add
s/<//g;
s/>//g;
or use the tr operator.

You could try solving the problem a different way.
Look at the Mail::Address module (in the MailTools
package on CPAN). It does the difficult bit for

Message-Id: <36D1C54D.E5444AEE@nt.com>
Hey there fellow perlers!
all of the following is on Win NT. Yay! (*sarcasm*)
I'm trying to write a script that is going to retrieve the content of a
directory on a file server, but the script is run on a different server.
the machine name is zbanb00b and the share name is Arch_pc
this is run on WIN NT server, on an NT network.
#########here is the code#########
#I love perl
###############################
$direct=3D"\\\\zbanb00b\\Arch_pc\\";
opendir(DIR, $direct) || die "cannot open $direct!!!\n";
### end of this fun script
now of course, when I run this I get the following output : =
"cannot open \\zbanb00b\Arch_pc\!!!"
I tried mapping it as X:\ and using "X:\\" as my value for $direct but
with no more success. I'm guessing that there is something with server
permission access that i'm missing. Any info would be much appreciated.
thanks, yer all very kind :)

perldoc -f splice
And if you don't know the index number, only the value, you can use a
lookup hash.

Assuming you don't know where 'james' is,
@array = grep $_ ne 'james', @array;
There are many useful Perl functions. Do `perldoc perlfunc` to get an
overview, then `perldoc -f grep` for details on this one.

Huh??? I showed how to do it using 'grep', but I have no idea what you
mean.

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.
]From: Russ Allbery <rra@stanford.edu>
]Date: 21 Sep 1998 19:53:43 -0700
]Subject: comp.lang.perl.moderated available via e-mail
]
]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
