How Does PHP's Conditional Operator Work?
Exploring PHP's Conditional Operators
PHP offers several operators to handle conditional statements, with the "?:" and ":" operators serving as essential tools.
The Conditional Operator (? :)
The conditional operator "?" acts like an inline "if-else" statement. It takes the form:
$x ? $y : $z
This expression evaluates to $y if $x is true (i.e., not false, null, or 0) and to $z otherwise. For example:
($request_type == 'SSL') ? HTTPS_SERVER : HTTP_SERVER
This expression returns HTTPS_SERVER if $request_type is 'SSL' and HTTP_SERVER otherwise.
Short Form (? :)
PHP provides a short form for the conditional operator:
$x ?: $z
This form evaluates to $x if $x is true and to $z if $x is false.
Distinguishing Ternary Operator
While the conditional operator is commonly referred to as the "ternary operator," this designation is actually a misnomer. Ternary operators have three operands, and "?" is just one of many ternary operators in PHP.

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 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.

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.
