Laravel:如何在类中创建动态函数(方法)(使用foreach循环)

class MyClass
{
    private $dynamicFunctions = [];

    public function __call($name, $arguments)
    {
        if (isset($this->dynamicFunctions[$name]) && is_callable($this->dynamicFunctions[$name])) {
            return call_user_func_array($this->dynamicFunctions[$name], $arguments);
        }
        throw new \BadMethodCallException("Method {$name} does not exist.");
    }

    public function addDynamicFunction($name, $function)
    {
        $this->dynamicFunctions[$name] = $function;
    }
}

$myObject = new MyClass();

// 使用foreach循环添加动态函数
$dynamicFunctions = [
    'sayHello' => function () {
        return 'Hello!';
    },
    'calculateSum' => function ($a, $b) {
        return $a + $b;
    },
];

foreach ($dynamicFunctions as $name => $function) {
    $myObject->addDynamicFunction($name, $function);
}

// 调用动态函数
echo $myObject->sayHello(); // 输出：Hello!
echo $myObject->calculateSum(2, 3); // 输出：5
