问题:

We use PHP7, latest MongoDB PECL package (1.2.2) - Laravel 5.3 - jenssegers/laravel-mongodb 3.1

I want to use GridFS. It's normally available into the MongoDB PECL package but there are no documentation nor working code example.

回答1:

You can use Bucket class for upload and download documents to mongodb grid on mongo-php-library 2.2 driver.

//upload file
$bucket = \DB::connection('mongodb')->getMongoDB()->selectGridFSBucket();
$resource = fopen($file_path, "a+");
$file_id = $bucket->uploadFromStream($file_path, $resource);

//download file
$bucket = \DB::connection('mongodb')->getMongoDB()->selectGridFSBucket();
$file_metadata = $bucket->findOne(["_id" => $file_id]);
$path = $file_metadata->filename;

if(!file_exists($path)) {
    $downloadStream = $bucket->openDownloadStream($file_id);
    $stream = stream_get_contents($downloadStream, -1);
    $ifp = fopen($path, "a+");
    fwrite($ifp, $stream);
    fclose($ifp);
}

You can go through this link. This shows how you can use gridFS with Laravel-mongodb and also you might need to update your mongo db drivers for this.

Another link for your reference.

Though there is not a sample code provided there, but it would help you if you have worked over Mongo with Laravel.

Hope it would help you
