在 Laravel 框架之外使用数据库查询构建器及 Eloquent ORM
在Laravel 框架核心代码的 illuminate/database包中,有一个 Capsule目录, 该目录下有一个 Manager.php文件,如果要在 Laravel 之外使用 Illuminate Database 组件,就要通过该文件实现。以Yii2 为例,我们首先在项目根目录下运行使用如下 Composer 命令安装该依赖包:
composer require illuminate/database ~5.1
这样在 vendor目录下现在就有了 illuminate/database包,接下来我们修改入口文件 index.php如下:
<?php// comment out the following two lines when deployed to productiondefined('YII_DEBUG') or define('YII_DEBUG', true);defined('YII_ENV') or define('YII_ENV', 'dev');require(__DIR__ . '/../vendor/autoload.php');require(__DIR__ . '/../vendor/yiisoft/yii2/Yii.php');//引入加载 Eloquent ORM 的启动文件require((__DIR__.'/../system/eloquent/Start.php');$config = require(__DIR__ . '/../config/web.php');(new yii\web\Application($config))->run();
然后我们到项目根目录下创建 system/eloquent/Start.php,编辑文件内容如下:
<?php$database = [ 'driver' => 'mysql', 'host' => DB_HOST, 'database' => DB_NAME, 'username' => DB_USER, 'password' => DB_PASSWORD, 'charset' => 'utf8', 'collation' => 'utf8_unicode_ci', 'prefix' => DB_TABLEPREFIX,];use Illuminate\Container\Container;use Illuminate\Database\Capsule\Manager as Capsule;$capsule = new Capsule;// 创建链接$capsule->addConnection($database);// 设置全局静态可访问$capsule->setAsGlobal();// 启动Eloquent$capsule->bootEloquent();
最后,我们可以到 models目录下创建模型类如下:
<?phpnamespace app\models;use Illuminate\Database\Eloquent\Model;class User extends Model{ protected $table = 'user';}
这样我们就可以在代码中以 Eloquent 模型类的语法使用 User 模型了。关于 Eloquent ORM 的使用方法,可参考Eloquent ORM 文档。

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,

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.

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.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

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.
