PHP Mongodb driver connection and insert

[ludo1960]

Hello guys,

I've installed the mongoDB PHP driver using "sudo pecl install mongodb"

Testing shows driver is installed correctly and it appears nicely in phpinfo():

ludo@aegir:~$ php7.2 -i | grep -i mongodb
mongodb
MongoDB support => enabled
MongoDB extension version => 1.5.3
MongoDB extension stability => stable
mongodb.debug => no value => no value 

For connecting I've got:

   $db = new MongoDB\Driver\Manager("mongodb://localhost:27017"); 

Now I want to define a collection and insert a record, i've been using code from here  https://www.php.net/manual/en/set.mongodb.php:

$collection = $db->mydatabase->mytable;

$result = $collection->insertOne( [ 'name' => 'test', 'item' => 'testitem' ] );

But this fails  Notice: Undefined property: MongoDB\Driver\Manager::$mydatabase in /var/www....

Has anyone got a workingg example of defining and inserting into mongoDB. Seems the driver was updated fairly recently and so stuff on the internet is not always relevant.

unfamiliar with Mongodb so this may be a silly question but what is this line saying:

 $db = new MongoDB\Driver\Manager("mongodb://localhost:27017"); 

Is "MongoDB\Driver\Manager"  a function name that is part of the mongodb interface?   To me it looks more like a path (without quotes) so I am puzzled.

Mongo has its own PHP classes. Is this what you are using?

Sorry, the link is here https://www.php.net/manual/en/set.mongodb.php there is our chum MongDB\Driver\Manager .

It looks to me like you want client not manager. In any case have you verified the path? You should be checking $db to make sure it is set.

Thanks for advice, wasn't getting anywhere till I found this https://www.php.net/manual/en/mongodb.tutorial.library.php now it works a treat, Once installed, you have access to all the mongo goodies https://docs.mongodb.com/php-library/current/

MongoDB\Client was indeed correct! Thanks again!
