mod_perl variables

["tony@clearfox.com" <to...@clearfox.com>]

 Hello Everyone,

 I have an issue that I am working on. I always ask questions that I 
have to a forum before writing the list just in case someone in the 
forum knows the answer. Usually I don't get any responses.

 I started this thread,

 http://www.tek-tips.com/viewthread.cfm?qid=1104388&page=1

 Will someone take a look and see if my last question can be answered. 
The first two posts will provide context for my situation. My handle is 
perl21

 I was following some advice from a fellow named Fish.

 In my last post in that thread I ask how to make my mod_perl script 
mess up the variable assignment of $html without using my or local

 Thank you,
 Tony

Tony,

Your questions about scoping are pretty common ones for beginning Perl
users.  May I suggest that you pick up a good book, like "Learning
Perl"?  That will go a long way towards clearing these things up for
you.

I'd also suggest reading this document:
http://perl.apache.org/docs/1.0/guide/porting.html

And I think you'll do better asking your questions on perl-specific
forums than on that one you tried before.  Take a look at perlmonks.org,
or one of the beginner lists shown here:
http://lists.cpan.org/

Ok,

I went to google and did some more searching, this time just about the
my var.

I wrote this for an example of BAD use of $variable based on the
article I found.

I believe this demonstrates the coding in my website currently online.
lol, which is failing periodically.

---------------------------------------------------------------
my $i = 1;
my $variable;

if($i > 0)
{
   $variable = "Hello World!";
   print_it();
}

sub print_it()
{
   print "$variable<br>";
   $variable=1;
}


{
   my $variable = "True";
   print "$variable<br>";
}

print "$variable<br>";
---------------------------------------------------------------

When I run it for the first time I get

Hello World!
True
1

Every time after that I get

1
True
Hello World!

Until the process dies and it runs in a new thread.

I believe this is the demonstration of my problem right? I'm pretty
sure I understand now.

Thanks for the tips mate! I'll post this as my fix in the forum.
Tony

 Thank you for the response.

 I am sure going to start using strict.

 But one thing, why doesn't my example of NOT using strict, my, our, or 
local ever fail.

 Shouldn't it confuse the $html var with the value of the $html var in 
the parent file.

 Any ideas on what kind of an example will demonstrate to me the 
variable problem I'm having in a small test program. I'm trying to make 
a program that will show the effects of not using strict and declaring 
the $vars. I want to be able to get it to mess up, and then declare the 
$vars and see it work differently.

 I am trying to do this because I do not understand how the $vars are 
treated differently when not declared.

 Thanks a lot!
 Tony

It might be that your variable aren't scoped properly.
Try:

use strict;

my $variable
or
our $variable
to keep the variable scoped to the packages they're in.
