You want to match a key based on a substring? and print all values that match? You can use the Tie::Hash mentioned above or just to match a substring you can do... 
for(keys %category) {
  print "$category{$_}\n" if /\Q$variable\E/i;
}

the \Q \E makes sure that you match the characters in $variable the way they are, (other a \ could screw you all up, or a . or a *, etc) and the i at the end makes it case-insensitive (often good in substring matching). Does that help?
