Q: I have an array that keeps returning matches in a string, each match must be inserted into a hash as an empty key (..)

If i judge by your code, you want empty values. Anyway empty keys does not make sense. Because each key of a hash must be unique within the hash set of keys

$hash{$_}=  '' for @array;

usually conunting number of matches for each strings makes more sense:

$hash{$_}++ for @array;
