If you have a question on how to do something in Perl, or you need a Perl solution to an actual real-life problem, or you're unsure why something you've tried just isn't working... then this section is the place to ask. Post a new question!

However, you might consider asking in the chatterbox first (if you're a registered user). The response time tends to be quicker, and if it turns out that the problem/solutions are too much for the cb to handle, the kind monks will be sure to direct you here.

Strange behaviour with Arrays and print?

    Hi,
    I'm currently refreshing my Perl experience by reading some books. During testing some scripts, I've noticed a strange behaviour during the following script:
    #!/usr/bin/perl binmode(STDOUT, ":utf8"); use 5.010; use strict; use warnings; use diagnostics; use utf8; my @fred; my $fred; $fred = "HALLO"; $fred[0] = "eins"; $fred[1] = "zwei"; $fred[2] = "drei"; $fred[3] = "vier"; $fred[4] = "fünf"; $fred[5] = "sechs"; $fred[6] = "sieben"; $fred[7] = "acht"; $fred[8] = "neun"; $fred[9] = "zehn"; print @fred; print "\n"; print @fred."\n";
    The output result is the following:
    einszweidreivierfünfsechssiebenachtneunzehn 10
    Why is the array counted if I use a new line?
    Is this normal and why?

    Thanks!

    Kind regards,

    Pingu

    I am building a simple web tool for a client. It will query a database and display some data. They will be able to search, sort, etc., so a simple javascript tool can handle the display. I want to use perl on the back end, as I have done in other situations. It has been suggested that I implement it via REST and then I can add new features fairly easily (this client likes to request that).

    I've read modern ways of doing web services. I've also read Apache2::REST. I don't see many servers using the latter, even though it looks good. Is something better? I don't want to do it all from scratch, of course.

    i am not able to get value in last_insert_id() after insert operation in sybase database. I had to use do statement instead of prepare statement for both insert and update operations to get value from last_insert_id(). Does anyone know the reason of this behavior?

next and last within subs

    I'm looping through the contents of an array.

    Before each iteration of the loop is completed, I want a couple of things done (increment a count, print some debug info, and a few other things). There are a number of conditions that cause the loop to move on to the next one early so my though is to put these into a subroutine and call that. However, one of these things is:

    if ($x > $stop) { last; } elsif ($y ne $text) { foobar(); } else { next; }

    So of course I get the warning "Exiting subroutine via last" (or next)

    Is there a good way of doing this without having to put that snippet of code into every place where I need to move the loop forward?

    This message is for all my Perl Monks; I am new to Perl and still wet behind the ears. But I do remember some things my parents taught me; why reinvent the wheel is someone else has already done it. I have a large Brocade switch environment crossing across multiple networks. Does any of my Monks scriptures have any scripts they would be willing to share with the new guy on the block? My workstation is Windows 7, 32 bit.
How to retain a value passed from another link to a script

    favorite I am calling a script from a HTML Template giving it a value to load the script as follows:
    <a href="orddetails.pl?go=Details&orderid=<!-- TMPL_VAR NAME=OrderID - +->">Details</a>
    The script gets executed with the value passed however I cannot use this value in other routines within the same script i.e. orddetails.pl, so the question is how can I retain this value, I am already declaring a Global variable for it :
    my $orderid = $q->param('orderid');

    I'm doing Data Warehourse related work. I have lots of files (size is about 1G for each), which are extracted from Oracle and need to be processed. Here I can use Java and Perl based on the host environment. But I'm not sure which kind of language can have a better performance to process such kind of big text file? Anyone can give me some suggestions? Thanks a lot.
