GridFS is not functional

Dear developers!

I've installed latest mongodb driver from pecl (mongodb 1.2.4 stable; git master repo was also tested) and php 7.0 (ubuntu xenial repository).

In function openDownloadStreamByFile declared in Bucket.php after call of:

        $context = stream_context_create([
            self::$streamWrapperProtocol => [
                'collectionWrapper' => $this->collectionWrapper,
                'file' => $file,
            ],
        ]);

$context is always NULL.

This is a bit odd, as stream_context_create() is only responsible for creating a data structure to encapsulate its two array arguments and return a corresponding resource.

Did you dump $context after this line to determine it was null?

I'd be curious what the following yields in your environment:

$context = stream_context_create(['gridfs'=>['collectionWrapper' => 'foo', 'file' => 'bar']]);
var_dump($context);
var_dump(stream_context_get_options($context));

I would expect:

resource(155) of type (stream-context)
array(1) {
  ["gridfs"]=>
  array(2) {
    ["collectionWrapper"]=>
    string(3) "foo"
    ["file"]=>
    string(3) "bar"
  }
}

Thank you for reply.

I've used error_log(var_export($context, true)) instead of var_dump(). It prints NULL. var_dump() is not :)

Sorry, it seems that I can't download file from GridFS by another reason, but don't sure why.

Thank you anyway!

I just realized there was an error in the GridFS tutorial, which suggested using file_get_contents() on the readable GridFS streams instead of stream_get_contents(). I've fixed that in #340 and should have it deployed shortly.

Assuming you're experiencing a separate issue and have additional questions, feel free to follow up in a new issue and we'll try to sort it out.

That's it! Thank you again!
