Examples
--------
.. code-block:: php
<?php
$bucket = (new MongoDB\Client)->test->selectGridFSBucket();
$stream = fopen('php://temp', 'w+b');
fwrite($stream, "foobar");
rewind($stream);
$bucket->uploadFromStream('b', $stream);
$cursor = $bucket->find(
['length' => ['$lte' => 6]],
[
'projection' => [
'filename' => 1,
'length' => 1,
'_id' => 0,
],
'sort' => ['length' => -1],
]
);
var_dump($cursor->toArray());
The output would then resemble::
array(1) {
[0]=>
object(MongoDB\Model\BSONDocument)#3015 (1) {
["storage":"ArrayObject":private]=>
array(2) {
["filename"]=>
string(1) "b"
["length"]=>
int(6)
}
}
}
