string mutation with accented letters in php code

Question

I have a string replacement that includes accented letters. I also used already a normalizer so that I have the same encoding and I cannot remove the diacritics because I need them for my output. My Code:

 $word = array("bā","ba");

for($i=0;$i<count($word);$i++)
{

    $accented = array("ā","ē","ī","ō","ū");

    $last = substr($word[$i],-1);


    if (    in_array($last,$accented)) { // replacement of the array with the accented letters
        $word[$i] = rtrim("x",$word[$i]);
    }



}

How can I modify my code so that it works for accented letters?

@Hallur I do not understand your question. It is simply a code that does only not work because of the accented letters in `$accented` — Moe Joe, Nov 21 '16 at 20:52
Yes, I understand that... but why doesn't it work, what are you trying to achieve? — , Nov 21 '16 at 20:52
@FelippeDuarte There should be a replacement of the array element of `"bā"` by `x`. So at the end I should get `Array ( [0] => x [1] => bam )` — Moe Joe, Nov 21 '16 at 20:54

Use mb_substr:

$last = mb_substr($word[$i],-1);

It will work properly with accenteded letters.

Output will be

Array (
    [0] => x
    [1] => bam
)
