Values in UTF-8 being encoded as NULL in JSON

Question

I have a set of keywords that are passed through via JSON from a DB (encoded UTF-8), some of which may have special characters like é, è, ç, etc. This is used as part of an auto

Try sending your array through this function before doing json_encode():

= '30') {
        return false;
    }

    /* step through inArray */
    foreach($inArray as $key=>$val) {
        if(is_array($val)) {
            /* recurse on array elements */
            $newArray[$key] = utf8json($inArray);
        } else {
            /* encode string values */
            $newArray[$key] = utf8_encode($val);
        }
    }

    /* return utf8 encoded array */
    return $newArray;
}
?>

Taken from comment on phpnet @ http://php.net/manual/en/function.json-encode.php.

The function basically loops though array elements, perhaps you did your utf-8 encode on the array itself?
