I am not getting any errors and my $results is not showing a value

I know there are better ways of doing this. I have done it using built in functions. I am trying to gain a better understanding of using a for loop within another for loop. The end result is to count how many times each unique character shows up in the original string. I dont see where my logic is flawed yet its not working so it must be my logic.

Solution

The for loop breaks when $lcv2 == $len

 for($lcv2 = 0; $lcv2 < $len; $lcv2++)

and the if statement is checking for $lcv2 == $len

$results .= $temp_unique_variable . " ". "(".$count . ")";

will never happen
