Need help with perl loop!


Hello.

Here is the problem.
My cgi script receives variables.

@pairs = split(/&/, $query);
foreach $pair (@pairs) {
($name, $value) = split(/=/, $pair);
$variable{$name} = $value;

$name is $item_name1, $item_name2, $item_name3, $item_name4 ... etc

I would like to make a loop:

for ($count = 1; $count <= 100; $count++) {
($item_name,$item_number) = split(/\|/, $variable{'item_number$count});
print "$item_no, ";
}

however this does not work. I'm sure taht the problem is in:
$variable{'item_number$count}

What is the correct way of saying this in PERL?
Thanks.

$variable{"item_number$count"}
or
$variable{'item_number'.$count}
or
$variable{"item_number".$count}
The first variant looks the better one...
BestRegards,
Oleg

Thanks Oleg.

$variable{"item_number$count"} works.

Regards,
