Hello,
function return types should not depend on the outside context (spawn, hook,
ini, etc.) because when the code gets more complex, it's very hard to find the
outside context.
So file_get_contents() should always return string|false,
file_get_contents_async() should always return a promise object.
From the example I would expect it like this:
$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 = $promise->await();
$content2 = $promise->await();
$content3 = $promise->await();
PHP got very successful by making things easier than in C, this should be the
path to continue.
Best Regards
Thomas
