CodeIgniter 安装分为四个步骤：
- 解压缩安装包。
- 把 CodeIgniter 文件夹和里面的文件上传到你的服务器。通常 index.php 在根目录。
- 用任何文本编辑器打开 application/config/config.php 去设置你的网站根 URL。如果你打算使用加密或 Session，请设置你的加密密钥。
- 如果你打算使用数据库，用任何文本编辑器打开 application/config/database.php 去设置你的数据库参数。
如果你希望通过隐藏 CodeIgniter 文件的位置来增加安全性，你可以修改 system 和 application 目录的名字，把它改成任何你想改的。如果已经修改了名字，你必须打开你主目录下面的 index.php 文件设置里面的 $system_folder 和 $application_folder 变量，把它设成你新改的名字。
为了安全考虑,system 和application 两个文件夹应放到网站的根目录，并拒绝浏览器的直接访问。在默认设置下, 在每个文件夹中都有一个.htaccess配置文件以拒绝直接访问, 但是当把代码部署到生产环境时最好移除他们，因为生成环境的web服务可能会改变或不支持.htaccess的配置.
如果你移动了以上两个文件夹,请打开主目录下的index.php文件并编辑$system_folder 和$application_folder 两个变量, 最好使用绝对路径进行替换, 例如：'/www/MyUser/system '.
以上就是全部安装过程！

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 late static binding in PHP (static::).
Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

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.
