微型 PHP 框架：FocusPHP
FocusPHP
FocusPHP是一个微型PHP框架
TODO
完善docker开发环境
增加后台管理
框架与项目分离
完善单元测试，使用Travis CI持续集成
备注
数据库文件中，username=admin, password=administrator
安装使用
composer require aicode/focusphp
MVC支持
框架本身可选的对MVC提供了支持，只需要在创建Focus\Server对象时注册Focus\MVC\Router对象即可。
$server->registerRouter(new Focus\MVC\Router('Demo\Controllers'));创建Focus\MVC\Router是需要提供控制器命名空间作为参数，这样框架就回到该命名空间下寻找适合处理当前请求的控制器。
视图对象
视图类需要实现Focus\MVC\View接口，框架内置了一套简单的视图实现Focus\MVC\SimpleView， 该实现使用.php文件作为视图文件模板，在模板文件中，直接使用原始的PHP语法即可。
默认视图Focus\MVC\SimpleView提供了layout支持。
隐藏的模板变量
| 变量名 | 说明 |
|---|---|
| __body__ | 解析模板后的内容，该变量只在layout中可用 |
| __data__ | 给模板对象传递的字符串数据（无key） |
框架异常消息
| 消息 | 含义 |
|---|---|
| INVALID_ROUTER | 路由不合法 |
| INVALID_ROUTER_ARGS | 路由参数不合法 |
| INVALID_ROUTER_FUNC | 路由规则执行函数不合法 |
| NONSUPPORT_PHP_VERSION | PHP版本不支持，请使用5.6.0以上版本 |
| CONFIG_FILE_NOT_FOUND | 配置文件不存在 |
| INVALID_CONFIG_FORMAT | 不合法的配置文件格式 |

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
How does PHP type hinting work, including scalar types, return types, union types, and nullable types?
Apr 17, 2025 am 12:25 AM
PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

How do you prevent SQL Injection in PHP? (Prepared statements, PDO)
Apr 15, 2025 am 12:15 AM
Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
PHP and Python: Code Examples and Comparison
Apr 15, 2025 am 12:07 AM
PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.
PHP: Handling Databases and Server-Side Logic
Apr 15, 2025 am 12:15 AM
PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.
