I'm sorry, the correct example should be:
$promise1 = file_get_content_async("file1.txt");
$promise2 = file_get_content_async("file2.txt");
$promise3 = file_get_content_async("file3.txt");
// do sth else
$content1 = $promise1->await();
$content2 = $promise2->await();
$content3 = $promise3->await();
Best Regards
