PHP base64_decode乱码要怎么弄啊?

Jun 23, 2016 pm 01:29 PM

比如说我现在要decode下面的字符串
$code = 'MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA88pPKPqRTcVGKcVNrphzUtq9hs1eSgyO/+g9DEfOVeeHlhaEhnYPabBJkpCayg3wTUKkBIWF5iPbPKKQp5zzdcWyvUXRcrHPzW77zm7HeraPT+YpXJlHjOdhERrGWKglvZmcVbcBLTr8mOlH3JjWmRf51G+LKPjT3OhVcJqCPwF+gC5CggyYiuiVN2OtvVjt2Tb2cxrjtVLbRCKTBq+4EpabkkEzWmurWLtrFT2N2ANDRDtfTmSpeQdHlzenlbWOFk8r3ty3/UiAP4HY53o1pvj5zDo5vZwHe25aoFHxSEJ3q/8H1OlCjbdeEeyTXA8IBqO5tNYRutS++8HlerZ4rQIDAQAB';
$tests=base64_decode($code);
var_dump( $tests );
输出后是:

有没有大神告诉我这个咋弄啊

显然他还做了某种处理
这要看是什么项目的数据了

这要看是什么项目的数据了

没有任何处理啊,我在举个列子:
$mod='d61df77df0b16df298c4e87e0f281ff5262684e486c4b495f23997ec7c81bb8a70c7ed314a667b0f098bb608a967db6be4a820e1b9960accebd2360654ef1825e8198e1d957e9e280c151bb01163066809e732c200cb0e9c61ca6567e25efa208bf3629dec0e29a89d96433107c26c7c29a6e4a12a4dd4b8a2b89a61ef3f3267';
$exp='010001';
$key=base64_encode ( hex2bin ( "30819f300d06092a864886f70d010101050003818d0030818902818100{$mod}0203{$exp}" ) );
$tests=base64_decode($key);
var_dump( $tests );$tests=base64_decode($key);
var_dump( $tests );
输出内容是:

hex2bin 

为什么要用到hex2bin函数
把十六进制值转换为 ASCII 字符?

$tests=base64_decode($key);
var_dump( $tests );$tests=base64_decode($key);
var_dump( $tests );
输出内容是:
确定是hex2bin 而不是bin2hex?

这就不知道你们要讨论什么问题了
正因为数据中有不可打印的字符,所以才使用了 base64 编码进行交换
要想知道数据的真实含义,至少需要看程序是怎么使用它的

感谢大家,问题我已经解决了,通过hex2bin转码后是显示不出来的,我做这个主要是关于JAVA和PHP的RSA的验签问题,由JAVA端使用ras签名后,传给PHP端做验签,由于PHP只能使用openssl生成的pem文件来做验签,而java端只给出了一串1024位的16进制的公钥字符串,弄了好久了,昨天晚上才弄好。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
