Import db for project PHP

Hello everyone, everything good?

I’m the following doubt, well after the easy engine started using docker, in my opinion it got really bad.

I would like to know how to import a database into my PHP project, well I’m not talking about a wordpress site I’m talking about a PHP project.

I do not know how to do this, now with the docker it seems that made it even more complicated.

I await feedback on the subject.
