如何获取U+010F对应的字符?
header('Content-Encoding: UTF-8');
function mb_html_entity_decode($string)
{
if (extension_loaded('mbstring') === true)
{
mb_language('Neutral');
mb_internal_encoding('UTF-8');
mb_detect_order(array('UTF-8', 'ISO-8859-15', 'ISO-8859-1', 'ASCII'));
return mb_convert_encoding($string, 'UTF-8', 'HTML-ENTITIES');
}
return html_entity_decode($string, ENT_COMPAT, 'UTF-8');
}
function mb_ord($string)
{
if (extension_loaded('mbstring') === true)
{
mb_language('Neutral');
mb_internal_encoding('UTF-8');
mb_detect_order(array('UTF-8', 'ISO-8859-15', 'ISO-8859-1', 'ASCII'));
$result = unpack('N', mb_convert_encoding($string, 'UCS-4BE', 'UTF-8'));
if (is_array($result) === true)
{
return $result[1];
}
}
return ord($string);
}
function mb_chr($string)
{
return mb_html_entity_decode('&#' . intval($string) . ';');
}
var_dump(hexdec('010F'));
var_dump(mb_ord('ó')); // 243
var_dump(mb_chr(243)); // ó
