如何直接从PHP运行Mongo Shell Query？

Question

I want to run MongoDB raw query directly from PHP.

My query is like below.

var document_id = db.Document.aggregate([{$project: {"creationDate":1,'_id':1}},{$match: {"_id":ObjectID("5aa7a8852f4b3e2e86004837")}}]).toArray();

document_id = document_id[0]['_id'];

var upload_id = db.Upload.aggregate([{$project: {"creationDate":1,'_id':1}},{$match: {"_id":ObjectID("5aa7a8852f4b3e2e86004837")}}]).toArray();

upload_id = upload_id[0]['_id'];

and get result of those two variable document_id & upload_id of concat or multiple or addition.

( FYI: In real, I won't concat or multiply ids it is just for example. )

I have checked "http://php.net/manual/en/book.mongodb.php" for reference but nothing found useful.

Can anyone guide me on that ?

Version of MongoDB & PHP MongoDB driver I am using.

MongoDB version 3.6

MongoDB PHP Driver version 1.5
