    I think you can use google reCAPTCHA as a strong solution.

    You can use pspell_check() funtion in PHP 8.1.0

    <?php
$pspell = pspell_new("en");

if (pspell_check($pspell, "testt")) {
    echo "This is a valid spelling";
} else {
    echo "Sorry, wrong spelling";
}
?>

    Detail page in here: https://www.php.net/manual/en/function.pspell-check.php

    Also for full comment function could be like:

    <?
function SpellCheck($comment) {
    $pspell_link = pspell_new("en");
    preg_match_all("/[A-Z']{1,16}/i", $comment, $words);
    for ($i = 0; $i < count($words[0]); $i++) {
        if (!pspell_check($pspell_link, $words[0][$i])) {
            $comment = str_replace($words[0][$i], "<font color="#FF0000">" . $words[0][$i] . "</font>", $comment);       
        }
    }
    return $comment;
}
?>
