Question

I am trying to check if a database is connected in Laravel.

I\'ve looked around the documentation and can\'t find anything. The closest thing I\'ve found is this, bu

Answer 1

You can also run this:

php artisan migrate:status

It makes a db connection connection to get migrations from migrations table. It'll throw an exception if the connection fails.

Answer 2

You can use this, in a controller method or in an inline function of a route:

   try {
        DB::connection()->getPdo();
        if(DB::connection()->getDatabaseName()){
            echo "Yes! Successfully connected to the DB: " . DB::connection()->getDatabaseName();
        }else{
            die("Could not find the database. Please check your configuration.");
        }
    } catch (\Exception $e) {
        die("Could not open connection to database server.  Please check your configuration.");
    }

Answer 3

Try just getting the underlying PDO instance. If that fails, then Laravel was unable to connect to the database!

// Test database connection
try {
    DB::connection()->getPdo();
} catch (\Exception $e) {
    die("Could not connect to the database.  Please check your configuration. error:" . $e );
}

Answer 4

Another Approach:

When Laravel tries to connect to database, if the connection fails or if it finds any errors it will return a PDOException error. We can catch this error and redirect the action

Add the following code in the app/filtes.php file.

App::error(function(PDOException $exception)
{
    Log::error("Error connecting to database: ".$exception->getMessage());

    return "Error connecting to database";
});

Hope this is helpful.

You can use alexw's solution with the Artisan. Run following commands in the command line.

php artisan tinker
DB::connection()->getPdo();

If connection is OK, you should see

CONNECTION_STATUS: "Connection OK; waiting to send.",

near the end of the response.

Answer 6

You can use this query for checking database connection in laravel:

$pdo = DB::connection()->getPdo();

if($pdo)
   {
     echo "Connected successfully to database ".DB::connection()->getDatabaseName();
   } else {
     echo "You are not connected to database";
   }
