How to add spell check to a php function

Question

I'm new to coding and I have been searching for a script to create a list of Anagrams, the following script is what I am using but it will display a list of words made up of every possible combination.

I'm wanting to add a spell check to the function such as pspell_check() which I found here visit https://www.php.net/manual/en/function.pspell-check.php

The idea is to only display words from the English dictionary.

Any help would be appreciated if anyone can show me how to add spell check to this code.

        { 
            $str = swap($str, $l, $i); 
            permute($str, $l + 1, $r);
