A list of HTML character codes can be found at: http://www.ascii.cl/htmlcodes.htm Note: To dencode a string that contains HTML character codes (in the format &#xx;), use the function unicode_decode(), listed in the comments of http://php.net/manual/function.html-entity-decode.php <?php /** * Encode each char in a string to its HTML code. * Characters encoded by this function can be decoded * by unicode_decode(). * * This function will work with PHP >= 3.0.9, 4, 5. * * @author Tim Burgan <timburgan@gmail.com> * @version 1.0.0 * @link http://timburgan.com/ * @link http://php.net/manual/function.htmlentities.php * @see http://php.net/manual/function.html-entity-decode.php * @param string $string String to encode * @param bool $encodeAll Optional.
