Mongodb通过Laravel / PHP检查连接是否正常

Question

I'm using laravel 5.2 and MongoDB 3.2.

I want to test if connection with is ok before my app starts (i can't use DB facade), in the monolog configuration. If connection is not ok, i will use logging in file.

By recommendation, i'm testing MongoClient, Mongo and MongoDB\Client, and using whatever is enabled.

I'm trying to test mongo connect as the following:

$mongoClient = new \MongoDB\Client('mongodb://localhost:27017');
$mongoClient->selectCollection('mydb', 'mycollection');

That's the return:

Client {   
    +manager: Manager {#21}
    +uri: "mongodb://localhost:27017"   
    +typeMap: [
        array => "MongoDB\Model\BSONArray",
        document => "MongoDB\Model\BSONDocument",
        root => "MongoDB\Model\BSONDocument"   
    ]
}

Finnaly, my questions:

• Exists a way to use DB facade before app starts?
• How and what is the right way to test MongoDB connection with PHP?

If you has another suggestion, i will be thankful.

Answer 1

using this way you can check MongoDB connection with PHP:

$connection = new MongoClient(); // connects to localhost:27017
$connection = new MongoClient( "mongodb://example.com" ); // connect to a remote host (default port: 27017)
$connection = new MongoClient( "mongodb://example.com:65432" ); // connect to a remote host at a given port
