5. A little difference between the atan function and the atan2 function

Introduction: atan and atan2 are arctangent functions. For example: there are two points point(x1,y1), and point(x2,y2); then the angle calculation method of the slope formed by these two points is: floatangle = atan( ( y2-y1)/(x2-x1) ); or float angle = atan2( y2-y1, x2-x1); The difference between atan and atan2: 1: The parameter filling method is different

6. javascript atan2() Calculate the angle from the y). This function has two parameters. The first parameter specifies the X coordinate of the point, and the second parameter specifies the Y coordinate of the point. Note the order of the parameters of this function. The Y coordinate is passed before the X coordinate. This article explains to you the basic syntax and usage examples of the atan2 function. Coders who need it can refer to it.

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 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.

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.

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.

Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Explain different error types in PHP (Notice, Warning, Fatal Error, Parse Error). Apr 08, 2025 am 12:03 AM

There are four main error types in PHP: 1.Notice: the slightest, will not interrupt the program, such as accessing undefined variables; 2. Warning: serious than Notice, will not terminate the program, such as containing no files; 3. FatalError: the most serious, will terminate the program, such as calling no function; 4. ParseError: syntax error, will prevent the program from being executed, such as forgetting to add the end tag.

What is the difference between include, require, include_once, require_once? What is the difference between include, require, include_once, require_once? Apr 05, 2025 am 12:07 AM

In PHP, the difference between include, require, include_once, require_once is: 1) include generates a warning and continues to execute, 2) require generates a fatal error and stops execution, 3) include_once and require_once prevent repeated inclusions. The choice of these functions depends on the importance of the file and whether it is necessary to prevent duplicate inclusion. Rational use can improve the readability and maintainability of the code.
