From the comments in the chr man page, one quick hack for turning an ordinal character number into a UTF-8 byte sequence:

从chr man页面的注释中，可以快速地将序号字符转换为UTF-8字节序列:

function unichr($u) {
    return mb_convert_encoding('&#' . intval($u) . ';', 'UTF-8', 'HTML-ENTITIES');
}

// unichr(0x610F) -> "\xE6\x84\x8F"

php have unicode encoding and decoding.. let u try on that

php有unicode编码和解码。让你试试

utf8_decode(); or utf8_encode();
