这又牵扯到 Unicode code points，为了更好的说明问题，我们需要把如上十进制转换成十六进制： shell> php -r 'echo dechex(19968);' 4e00 shell...> php -r 'echo dechex(40908);' 9fcc 在 Unicode 官方网站，我们能查到 Unihan Grid Index，其中 CJK Unified Ideographs...php $string = "博"; for ($i = 0; $i < strlen($string); $i++) { echo dechex(ord($string[$i])); }
