Edit my php script

I have a php script to list Anagrams of a word, all I need to do is add a word to the script and the out put will be a permutation of the word compared to the dictionary and then listed.

My problem is when I add some words the output is the same word repeated.

This happens whenever the word contains duplicate letters. When it swaps a letter with a copy of itself, such as the first and third letters in anagram, the new word is also in the dictionary, so it gets printed again.

Anagram gets printed 6 times, I’ve tried array_unique and many number of other things to remove duplicates.

What I need doing


Edit the current code so it doesn’t echo duplicate words, should be a simple fix for someone in the know but I’m still new to php and can’t get my head around it.



function permute($str, $l, $r, $pspell_link)


if ($l == $r) {

if (pspell_check($pspell_link, $str)) {

echo "<p>".ucwords($str)."</p>";





for ($i = $l; $i <= $r; $i++)


$str = swap($str, $l, $i);

permute($str, $l + 1, $r, $pspell_link);

$str = swap($str, $l, $i);




function swap($a, $i, $j)



$charArray = str_split($a);

$temp = $charArray[$i] ;

$charArray[$i] = $charArray[$j];

$charArray[$j] = $temp;

return implode($charArray);


$str = "anagram";

$n = strlen($str);

$pspell_link = pspell_new("en");

permute($str, 0, $n - 1, $pspell_link);
