print DB ("$i++\n");' is equal to $i . "++\n"
even if it were not a string and did increment $i, you're using the post-increment operator and it would increment AFTER it printed.

try this:
print DB ++$i . "\n";'

I've just woken up and my brain is in half rotation, but try this code..

#!/usr/local/bin/perl

	use CGI;
	my $query = CGI->new();

	
	my $db = "/home/data/user.txt";

	open(DB, $db);
		chomp($current_hits = <DB>);
	close(DB);
	$current_hits++;
	open(DB, ">$db");
	print DB "$current_hits\n";
	foreach $key (sort keys(%ENV)) { 
		print DB "$key = $ENV{$key}\n"; 
	} 
	close(DB);
	
	my $url = "http://bradyhouse.hypermart.net/home.html";

	print $query->redirect("$url");

Nah. This won't work.

First off you don't initialize the variable $i to be incremented, and then you don't store it anywhere so Perl doesn't know what it was left at to increment it for the next visitor.

The easiest way to solve this be to create another file just with a number stored in it, and then create a sub to fetch the number, increment it and print it back to the file. This will work as your counter, then.

Hope this helps.

ok..i have a code that takes the env vars and places them in a db (flatfile):

#!/usr/local/bin/perl

	use CGI;
	my $query = CGI->new();

	
	my $db = "/home/data/user.txt";

	
	open (DB,">>$db");
	print DB ("$i++\n");
	foreach $key (sort keys(%ENV)) { 
		print DB ("$key = $ENV{$key}\n"); 
	} 
	print DB ("\n");
	close DB;

	
	my $url = "http://bradyhouse.hypermart.net/home.html";

	print $query->redirect("$url");

i added the print DB ("$i++\n");', thinking for the first person, it would add the number 1 infront of the env vars....and the second person would be 2 and so on...but it doesnt work, it only prints ++' in front of the env vars

it is sort of a hit counter....just something that i want to see how many people come, and which visitor had what stats...

++ to the top of what?
are you making a hit counter type thing? is the results being written to file or database?
whats the code segment?
