目前比较新的 Linux 发行版都有一个默认配置，就是在同时支持 IPV4 和 IPV6 的服务器上，监听 IPV6 地址端口的时候，系统会自动监听对应的 IPV4 端口。
# 查看 bindv6only 的值
cat /proc/sys/net/ipv6/bindv6only 默认为0，就是自动绑定 IPV4 和 IPV6
取消自动绑定
sysctl -w net.ipv6.bindv6only=1
echo "net.ipv6.bindv6only = 1" >> /etc/sysctl.d/net-sysctl.conf我们经常使用的 Base64 编码用来对字符串或者字节数组进行编码转换，以方便存储。可是Base64 编码的结果可能会带有特殊字符，应用场景有限。
而 Base16 编码生成的结果是用[0-9A-F]十六个字符表示，可以用来生成字符索引和文件名等，应用范围比 Base64 要大的多。
缺点的话 Base16 编码的结果字符串比 Base64 编码的结果字符串要长， Base64 大概是1.3倍长，而 Base16 是原长度的两倍。
Base16 编码的原理是先获取字符串每个字节的二进制值，高位用0补充到8位。然后每4比特分割成一组，每组的二进制值转换成十进制，然后再对应到[0-9A-F]，对应的结果就是编码的值。
PHP 官方并没有 Base16 的编码实现，使用下面的函数就可以实现Base16的编码和解码。
function base16_encode($string)
{
$encode = '';
$chars = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'];
for ($i = 0; $i < strlen($string); $i++) {
$encode .= $chars[(ord($string[$i]) & 0b11110000) >> 4] . $chars[ord($string[$i]) & 0b00001111];
}
return $encode;
}
function base16_decode($encode)
{
$result = '';
for ($i = 0; $i < strlen($encode) / 2; $i++) {
$result .= chr(intval(substr($encode, $i * 2, 2), 16));
}
return $result;
