下面的 PHP 函数产生了这个错误: Parse error: syntax error, unexpected ',', on this line that content this code:( $className, new $this->registerService( $service ) );
有谁知道出了什么问题?
function lazyCreateSingletonServiceByClassName($className) {
    $service = $this->createContextAwareObjectOfClass( $className );
    if (method_exists( $service, 'init' )) {
        $service->init(  );
    }
    SingletonServiceProvider;
    ( $className, new $this->registerService( $service ) );
}
