PHP反射:识别正确的构造函数

<?php

class MyClass {
    public function __construct($param1, $param2) {
        echo "Constructor called with params: $param1, $param2";
    }
}

// 创建反射类实例
$reflectionClass = new ReflectionClass('MyClass');

// 获取构造函数
$constructor = $reflectionClass->getConstructor();

// 获取构造函数的参数
$parameters = $constructor->getParameters();

// 打印参数信息
foreach ($parameters as $parameter) {
    echo "Parameter: " . $parameter->getName() . "\n";
}

// 实例化类并调用构造函数
$instance = $reflectionClass->newInstanceArgs(['value1', 'value2']);
?>

// 确保参数匹配
$instance = $reflectionClass->newInstanceArgs(['value1', 'value2']);

// 确保构造函数存在且可访问
if ($reflectionClass->hasMethod('__construct')) {
    $constructor = $reflectionClass->getConstructor();
    if ($constructor->isPublic()) {
        $instance = $reflectionClass->newInstanceArgs(['value1', 'value2']);
    } else {
        throw new Exception("Constructor is not public.");
    }
} else {
    throw new Exception("Constructor does not exist.");
}
