Can PHP code be evaluated within PHP echoes?

Utilizing PHP within PHP Echoes
Problem:
In scenarios with frequent usage of PHP snippets embedded in HTML, can PHP be utilized within PHP echoes? For instance:
<?php
echo "<?php the_author_meta('description'); ?>";
?>Answer:
No, PHP cannot echo PHP code to be evaluated further due to PHP's single-pass interpretation. The code provided will output the text "" instead of interpreting it.
PHP Entry and Exit:
However, it is possible to switch between PHP and HTML interpretation freely:
<?php echo "Interpreted by PHP."; ?> I am not interpreted by PHP. <?php echo "Interpreted again by PHP."; ?>
Alternative to Re-evaluated PHP Output:
If the goal is to output PHP code for re-evaluation, there are alternative approaches. Please provide a specific real-world example, and members of the Stack Overflow community will gladly assist.

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.
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.
