socket_last_error返回的错误号是多少?

socket_last_error  好像没错误

    //echo $buffer; 返回值是 142142142 一排

40之前都对的 网页上显示出connect OK. 这个了

   //printf("%s $msg
",$this->sendflag);
      //printf("%s $result
",$this->recvflag);

输出 
>>> VER=1.4&CON=1&CMD=Login&SEQ=112255&UIN=2810316641&PS=CA9ED0A4F6F2A06017F09D3CA53D030B&M5=1&LG=0&LC=812822641C978097&GD=5MWX2PF3FOVGTP6B&CKE=

你接收时需要打循环的么?1k就能收完?

另外,程序比网络快,你发完就直接收,那边可能还没来得及发呢,你的read可能一下子就跳过了,执行了close()


最后要说的是,你了解socket和通信机制么?
如果已经做过相关工作,可以忽略这个问题
如果完全新手,还是要花时间看看socket相关资料,光错误类型就几十个,而且几乎每次都发生的“错误”都有两三个,socket编程很多时候要通过判断错误来确认数据状态的,因为有些非致命“错误”是必然发生的,是传输结束的标志

tcp,能用curl就用curl吧。

很明显,你应该是已经将socket close了,还继续向socket 读取数据和发送数据。

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.

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.

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.
