使用构造函数调用helper类中的Laravel :：方法

// Helper.php
namespace App\Helpers;

class Helper
{
    public static function sayHello()
    {
        return "Hello, World!";
    }
}

// MyClass.php
namespace App\Services;

use App\Helpers\Helper;

class MyClass
{
    public function __construct()
    {
        // 在构造函数中调用 Helper 类的静态方法
        $message = Helper::sayHello();
        echo $message;
    }
}

// 在控制器或其他地方使用 MyClass
use App\Services\MyClass;

$myClass = new MyClass(); // 输出: Hello, World!

// MyClass.php
namespace App\Services;

use App\Helpers\Helper;
use Illuminate\Support\Facades\App;

class MyClass
{
    protected $helper;

    public function __construct(Helper $helper)
    {
        $this->helper = $helper;
        $message = $this->helper->sayHello();
        echo $message;
    }
}

// 在服务提供者中绑定 Helper 类
use App\Helpers\Helper;
use Illuminate\Support\ServiceProvider;

class MyServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->singleton(Helper::class, function ($app) {
            return new Helper();
        });
    }
}

// MyClass.php
namespace App\Services;

use App\Helpers\Helper;

class MyClass
{
    public function initialize()
    {
        $message = Helper::sayHello();
        echo $message;
    }
}

// 在控制器或其他地方使用 MyClass
use App\Services\MyClass;

$myClass = new MyClass();
$myClass->initialize(); // 输出: Hello, World!
