Why MongoDB Class doesn't work in Laravel?

问题

I want to use MongoDB in Laravel, This is my code in Controller :

public function create (Request $request) {
    $m = new MongoClient();
    $db = $m->selectDB("Laravel");      
    $collection = $db->selectCollection("Posts");
    $document = array( 
       "Title" => $request->input('Title'), 
       "Publisher" => $request->input('Publisher')
    );      
    $collection->insert($document);
}    

But when I click "Submit", It gives me an error :

Fatal error: Class 'App\Http\Controllers\MongoClient' not found

I have run MongoDB Server & also Wamp & I have Installed MongoDB & It's Driver for PHP ...

What is My Mistake ? (I should say that I haven't done any config for Laravel by using MongoDB, Is it needed ?)

回答1:

Laravel doesn't come with a driver for MongoDB.

If you want to use mongo with laravel you'll have to create your own class to deal with it or use this one:

laravel-mongodb
