I have an anagram solver on one of my sites that searches for words in a txt file and returns the results. It will return the results from 2 letter words first then as you scroll down up to 12 letter words. I like using a text file as my db because it returns the results so quickly.
I want to reverse the order of results so that it shows 12 letter words first then as you scroll down to 2 letter words. Here is my code and I will explain what changes I have made so far that produce errors and not the results I want. I am having a hard time understand it.
I will list my code as well as a link to download the txt file which is a word list if you need it.

What I have tried is simply trying to reverse a "for" loop, here is the loop that works currently. Note there are 2 locations where to loop exists.
The current "for" loop that works fine but shows results from 2 - 12
for($i = 0; $i < $wlen; $i++) {
and I tried to change it to this to try and reverse the order from 12 - 2
for($i = $wlen; $i > 1; $i--) {
If you notice $wlen is declared as a string length here, $word being the word someone inputs from a form field.
$wlen = strlen($word);
When I change the "for" loop I get an error at line 29 which is
foreach($b as $n => $c) {
Im confused about this error because $c is not declared anywhere before this point, yet the script works fine if you use the first "for" loop and not the second.
Any ideas?
