关于PHP中URL参数的传递问题
最近同事在维护一个PHP的网站，这个网站是很久以前开发的，之前负责维护的员工已经离职了，现在维护任务分配给我们信息技术部了，主要由这个同事负责。
现在要求把网站迁移到一个新的机房，所以需要重新配置一个主机，然后把网站移过来，折腾了几天，一切都OK了，但是在测试的时候，发现一个问题，就是所有的页面，如果地址栏中有参数，需要查询数据库的，那么这个页面就查不到数据，但是数据库连接是正常的。最开始以为是程序问题，但是后来发现只要有参数传递的页面都有这个问题，于是就推测不是程序问题，程序没有修改过，那么只可能是配置问题，但是配置没发现什么问题，最后还是只能借助google了。
最后查询的结果是php的版本之间有差别，有些默认开启的配置在php5中被关闭了，如在php4以前url后面的参数是自动填充到参数名称对应的变量中，如果url地址为view.php?id=1 ，那么在view.php页面中可以直接使用$id来去得参数id的值，这个对应的配置项为register_globals，在php4之前的版本中，默认是开启的，后面的版本是关闭的。于是就到C盘的
windows目录里面找到php.ini文件，将register_globals的值改为On，然后再测试，发现问题解决了。
为这个问题折腾了不少时间，特意记下来，以便下次再折腾。

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,

Explain the match expression (PHP 8 ) and how it differs from switch.
Apr 06, 2025 am 12:03 AM
In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
