为什么strpos()函数不能用变量查询?
strpos($str,"ABC");
这样可以。
$A="ABC";
strpos($str,$A);
这样就不可以。
这是为什么?
回复讨论(解决方案)
怎么可能呢
$str = "123ABCDEF";$A = "ABC";var_dump(strpos($str, $A));var_dump(strpos($str,"ABC"));
int(3)
显然是你传入的数据有问题
嗯,不是这个情况,我问题提的不对。
原本的样子是这个模样:
$sp=$ID[$home[$e]];
$location=strpos($myfile,$sp);
$sp的有值,但$location没有。
什么情况?
具体情况要具体分析
你把那几个变量都打印出来,看看问题出在哪里
哦,知道怎么回事了,$myfile根本就没这个字符串,我没注意看资源文档,应该检查一下的。
不好意思打扰了

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,

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.

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.

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.
