You don't need to be an utter cowdawg towards the OP -- strict and warnings are irrelevant to his issue.

I don't fully grok the semantics of foreach but I suspect the correct answer is as follows:

$sref = \$string sets $sref to point to the variable $string. All is well here. But then foreach enters the picture and localises $string -- this $string is only available to the inner loop. $sref continues pointing to the $string in the outer loop. Testing this without the string reference:

my $string = "I'm still here";
say $string;

my @array_of_strings = qw/foo bar baz quux/;

foreach $string ( @array_of_strings ) {
        say $string;
}
say $string;

# output
I'm still here
foo
bar
baz
quux
I'm still here

Yep, looks like what I described. Now, if you add the $sref, you'll notice it'll print the outer loop value for the whole time -- it points to the wrong $string.
