How to write multidimensional php array to mongodb with one request?

Question

PHP

There is a library https://github.com/mongodb/mongo-php-library , how to use it to write the entire multidimensional array at once, as for example it can be done in node.js (immediately pass an object to the insert).

Answer 1

Serialize array to JSON and save as string?

Answer 2

What is the question at all? If you use this library, then nothing changes, except for the name of the method:
Your entire multidimensional array will be saved and even possibly return the _id of the saved record.
