How to convert all characters in a string to HTML entities?

htmlentities() doesn't work for characters like ćĆČčŠšĐđŽž

<?php

function encode($string) {
    return mb_encode_numericentity($string, array(0x000000, 0x10ffff, 0, 0xffffff), 'UTF-8');
}

echo encode('ćĆČčŠšĐđŽž');

Result is ćĆČčŠšĐđŽž

There are no (named) entities for those characters.

You can see the list here. If you want to convert to numerical entities, see this answer.

Your recommended alternative function encode2() produces the following error: Parse error: syntax error, unexpected T_FUNCTION, expecting ')' on the line where the array_map is called

@A-OK It's written for PHP 5.3.

The character code of "ć", is 263, which as an HTML entity is ć, and so forth.

Convert first using htmlentities, then convert any characters which are outside the ASCII range in a second pass using preg_replace_callback and the regex "/[^\x00-\x7F]/".

It's widely known that some characters are not encoded with htmlentities();.

If you look at the docs, there are some posts with character maps you can use with str_replace()
