PHP echo vs PHP Short Echo Tags: A Comprehensive Examination of Safety and Performance
The safety and performance advantages and disadvantages of using PHP's short echo tag have been a subject of debate among developers. While some argue that using the short echo tag, =$function_here; ?>, is less safe and can slow down page load times, others advocate strictly using echo.
Defining the Short Echo Tag
Firstly, it's crucial to clarify that = is not a short open tag, but rather a shorthand echo equivalent to
Safety Considerations
When it comes to security, the output from both echo and the shorthand echo must always be encoded according to the output medium's rules. For example:
- HTML output: Encode using htmlspecialchars() to protect from HTML injection.
- JavaScript output: Encode using json_encode() to prevent JavaScript code vulnerabilities.
- Mixed HTML and JS output: Use both HTML and JavaScript encoding for comprehensive protection.
Performance Implications
The claim that the shorthand echo slows down page load times is inaccurate. Both echo and the shorthand echo are executed by the PHP engine with negligible performance differences. The factors that primarily affect page load times are database queries, file handling operations, and overall server performance.
Conclusion
While the shorthand echo tag offers a slightly concise syntax,

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.
