memory or from a stream. See the following diagram to see how GridFS splits | ||

I changed to $custom_bucket = $client->db->selectGridFSBucket(), so it still specifies the database

Use the ``MongoDB\GridFS\Bucket::delete()`` method to remove a file's collection | ||
document and associated chunks from your bucket. This effectively deletes the file. |

May be worth clarifying that this is going to delete a revision of a file. If another fs.files
document exists for that filename, it can still be read. And if users aren't aware of GridFS' revision behavior and selecting the most recent by default, they could be surprised to discover that they can still query for a filename after calling delete()
. The clarification should help avoid that.
Note that this also applies to rename()
. Common advice for both may be telling users to collect all IDs for a filename if they intend to rename or delete all of its revisions. I don't think you need example code for that (can be left as an exercise for the reader).

I see the new "File Revisions" notes for renames/deletes. Is there a DOCSP ticket to track future work of documenting the revision
option for download methods? That seems like it'd be generally relevant to all driver GridFS tutorials.

Revisions look good. Only significant suggestion is the change the downloadToStream()
and uploadFromStream()
examples to use actual files instead of php://temp
streams.

If you take my suggestion on the example code, these can be reduced to a single bullet that calls fopen()
on a local file. You can also note that we open the file in "binary read" mode (i.e. rb
).
For the download example, we would fopen()
or destination in "binary write" mode (i.e. wb
).

Renaming variable for consistency with the start-upload-from-stream
example code. This should require no changes to the RST.

I missed this earlier. The code below uses new MongoDB\Client(...)
so this use
statement has no effect. Consider removing it.
Alternatively, decide if you want to rely on use
statements for all class references in the interest of consistency. I see you're doing that for new ObjectId(...)
.
