多了从126的单元至130的单元。这样的话array_combine会报warning错误,Both parameters should have an equal number of elements。

如果要完全匹配,如何过滤126-130 单元的内容信息?


回复讨论(解决方案)

array_combine 函数需要参与运算的两个数组的长度一致,如果你不能保证这一点,就不要使用
你的 126-130 单元的内容并不在二维表中,当然需要单独处理

你或许可以
[83] => Part Information
作为二维表的开始
[126] => Supplier
作为二维表的结束

你或许可以
[83] => Part Information
作为二维表的开始
[126] => Supplier
作为二维表的结束

能不能写下范例?键值是不是一定要指定?还是只要值的结果就可以?

如何做,得由你决定
我举例中用 array_combine 只不过告诉你还可以这么做

我的意思是指定起始位置和终止位置这个如何做到?是依靠数组的值还是同样需要键值?

搞定了。由于最后五行是固定的,用了array_slice函数,再用了个array_diff函数就把后面的5行数据去掉了。非常感谢!

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.

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,

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.
