- 使用 Google Trace Event 格式输出
- 函数说明
- 函数分组
- 函数别名 (对匿名函数有用)
<?php// first thing to do, enable forp profilerforp_start(); // here, our PHP code we want to profilefunction foo(){ echo "Hello world !\n";}; foo(); // stop forp bufferingforp_end(); // get the stack as an array$profileStack = forp_dump(); print_r($profileStack);
结果:
Hello world !Array( [utime] => 0 [stime] => 0 [stack] => Array ( [0] => Array ( [file] => /home/anthony/phpsrc/php-5.3.8/ext/forp/forp.php [function] => {main} [usec] => 94 [pusec] => 6 [bytes] => 524 [level] => 0 ) [1] => Array ( [file] => /home/anthony/phpsrc/php-5.3.8/ext/forp/forp.php [function] => foo [lineno] => 10 [usec] => 9 [pusec] => 6 [bytes] => 120 [level] => 1 [parent] => 0 ) ) )

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.

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,

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.
