Sorry for the english, I just installed Linux.
The solution is to use a foreach loop.
If this is 1d array than you should use a function like this:

PHP קוד:

function ArrSpecialChars($array) {
    foreach($array as $key=>$val) {
        $array[$key] = htmlspecialchars($val);
    }
} 


But, if it is a 2d or more array you should use something recursive like this:

PHP קוד:

function ArrSpecialChars($array) {
    foreach($array as $key=>$val) {
        if(is_array($val)) {
            $array[$key] = ArrSpecialChars($val);
        }
        $array[$key] = htmlspecialchars($val);
    }
    return $array;
} 


Of cures this one will work for both cases.

Edit:
You can use this function as a master function, for strings to arrays..

PHP קוד:

function SpecialChars($text) {
    if(is_array($text)) {
        foreach($text as $key=>$val) {
            if(is_array($val)) {
                $text[$key] = SpecialChars($val);
            }
            $text[$key] = htmlspecialchars($val);
        }
        return $text;
    }
    elseif(is_string($text)) {
        $text = htmlspecialchars($text);
        return $text;
    }
    else {
        return false;
    }
}
