php 动态调用静态方法

// 确保类已经被加载
require_once 'MyClass.php';

$className = 'MyClass';
$methodName = 'myStaticMethod';

if (class_exists($className) && method_exists($className, $methodName)) {
    $className::$methodName();
} else {
    echo "类或方法不存在";
}

class MyClass {
    public static function myStaticMethod() {
        echo "静态方法被调用";
    }
}

function callStaticMethod($className, $methodName) {
    if (class_exists($className) && method_exists($className, $methodName)) {
        $className::$methodName();
    } else {
        echo "类或方法不存在";
    }
}

$className = 'MyClass';
$methodName = 'myStaticMethod';

callStaticMethod($className, $methodName);
