I believe that foreach makes a local copy in scope

If I correct the script like this:
I get this result: I get lv_num = 0 ????? why not 3
Weird to me....thought it will update the number correctly
Chanan

my @arr = (1,2,3,4,5);
my $lv_num = 0;
foreach $lv_num (@arr)
{
   print "Found $lv_num\n";
   last if ($lv_num == 3);
}

print "lv_num = $lv_num\n";

Hi All

I am running this simple foreach loop:
why do I get lv_num = <null> ? am I missing something ?
Thanks
Chanan


my @arr = (1,2,3,4,5);

foreach $lv_num (@arr)
{
   print "Found $lv_num\n";
   last if ($lv_num == 3);
}

print "lv_num = $lv_num\n";
