96位base64编码字符串MEQCIEJ4NhR0OXUOjKhYzH8+xlX4s8u6GzDPjYbaS8yK7BaAiByIgjUASGG6k6s5XuE8SaWWU6IL82qfpw876m6m3MlEw==怎么通过PHP能转换成128 位hex字符串结果是什么

可以使用PHP内置的base64_decode函数将base64编码字符串解码为二进制数据，然后使用bin2hex函数将二进制数据转换为hex字符串。

以下是代码示例：

$base64_str = "MEQCIEJ4NhR/0OXUOjKhYzH8+xlX4s8u6GzDPjYbaS8yK7BaAiByIgjUASGG6k6s5XuE8SaWWU6IL82qfpw876m6m3MlEw==";

$binary_data = base64_decode($base64_str);

$hex_str = bin2hex($binary_data);

echo $hex_str;

输出结果：
