A complete collection of PHP array sorting methods (compiled and contributed by Script School)
This article introduces the commonly used array sorting methods in PHP, including the usage of PHP array sorting functions, and the sorting methods of one-dimensional arrays, two-dimensional and multi-dimensional arrays in PHP. Friends who are interested should not miss it.
We know that in PHP programming, the content about PHP array sorting has always been a very important knowledge point. This section has compiled some articles about array sorting in PHP, including the usage of PHP array sorting functions, sorting methods and examples of one-dimensional, two-dimensional and multi-dimensional arrays in PHP. After familiarizing yourself with and mastering the methods and techniques introduced in this article, I believe that you will have no problem with programming and problems related to PHP sorting. The content is divided into three parts, as follows: 1, php array sorting function Several functions for php array sorting (with examples) php array_multisort multidimensional array sorting example php array functions array_map, array_multisort multidimensional array sorting examples The difference between php array sorting function array_multisort and uasort Detailed example of array multisort sorting principle in php Examples of application of krsort and asort functions in php array sorting 2. PHP one-dimensional array sorting PHP array sorting example code php array instance array sorting PHP array sorting example sharing (multiple sorting methods) PHP array sorting (ascending order, descending order and related issues) Summary of PHP array sorting method (Collection) php array sorting example (without built-in functions) PHP array sorting method sharing (bubble sort, selection sort) php simple array sorting method 3, php multidimensional array sorting Small example of php sorting two-dimensional array according to key value php two-dimensional array sorting (example) Two examples of php two-dimensional array sorting php sorts two-dimensional array PHP two-dimensional array sorting custom function php code for sorting a two-dimensional array by specified key values Learn to sort multi-dimensional arrays in php php multidimensional array sorting example PHP code for sorting multi-dimensional arrays by a certain value Two methods of php two-dimensional array sorting php multidimensional array sorting PHP compares the size sorting implementation code of values in multi-dimensional arrays |

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,

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.

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 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.

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.

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.

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.
