$criteria = array(), array $options = array()): bool|array
criteria
The filename or criteria for which to search.
options
An array of options for the remove operations executed against the
chunks and files collections. See
MongoCollection::remove() for documentation on these
options.
Returns an array containing the status of the removal (with respect to the
files collection) if the "w" option is
set. Otherwise, returns true.
Fields in the status array are described in the documentation for MongoCollection::insert().
Throws MongoCursorException if the "w" option is set and the write fails.
Throws MongoCursorTimeoutException if the "w" option is set to a value greater than one and the operation takes longer than MongoCursor::$timeout milliseconds to complete. This does not kill the operation on the server, it is a client-side timeout. The operation in MongoCollection::$wtimeout is milliseconds.
