simple UTF-8 to HTML conversion:
function utf8_to_html ($data)
{
return preg_replace("/([\\xC0-\\xF7]{1,1}[\\x80-\\xBF]+)/e", '_utf8_to_html("\\1")', $data);
}
function _utf8_to_html ($data)
{
$ret = 0;
foreach((str_split(strrev(chr((ord($data{0}) % 252 % 248 % 240 % 224 % 192) + 128) . substr($data, 1)))) as $k => $v)
$ret += (ord($v) % 128) * pow(64, $k);
return "&#$ret;";
}
Example:
echo utf8_to_html("a b č ć ž こ に ち わ ()[]{}!#$?*");
Output:
a b č ć ž こ に ち わ ()[]{}!#$?*
