Solution to content encoding error in PHP program in Firefox

The PHP program prompts when accessing Firefox: Content encoding error. The page you are trying to view cannot be displayed because it uses an invalid or unsupported compression format.

The PHP program prompts when accessing Firefox: Content encoding error. The page you are trying to view cannot be displayed because it uses an invalid or unsupported compression format. Under IE it just says 'This page cannot be displayed'. The program uses the ThinkPHP framework. After investigating the cause, it was found that it was caused by the use of ob_start('ob_gzhandler') in the program.

The solution is relatively simple: The following two issues may cause this problem. 1. The server does not support this compression format. You can use function_exists('ob_gzhandler') to determine. Solution: change ob_start('ob_gzhandler') to ob_start(); 2. When using ob_start('ob_gzhandler'), the content has been output before. Check the previous content and the content of the require include calling file. If it cannot be found, you can use ob_start() before calling other files, and use ob_end_clean () after calling to clear the output content;

The error I encountered was because there was output before ob_start, so the program could not run.

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.
