How to use uri with database name in php mongodb library

Question

I've probably spent more time than I should on this. I want to deploy PHP & mongodb applications with the help of Heroku.

Heroku mLab provides me the environment variable MONGODB_URI for accessing in PHP through getenv('MONGODB_URI') and this environment contains standard MongoDB URI:

mongodb://<dbuser>:<dbpassword>@dsxxxxxx.mlab.com:31899/heroku_lxxxxxx

which already contains an existing database name, but I have connected the string without it, as mentioned below:

$client = new MongoDB\Client("mongodb://localhost:27017");

$collection = $client->demo->beers;

So can I use the default Heroku's MONGODB_URI string or I have to parse_uri it and then pass that to PHP?

Answer 1

In MongoDB, the string “mongo://localhost:27017” basically means that the drive is connected to the localhost:27017 without any authentication whereas the Heroku manages your data in different servers and in that server it requires authentication. As you have mentioned your MONGODB_URI so your code will be:

$mongoHost = getenv('MONGODB_URI');

$client = new MongoDB\Client($mongoHost);
