Laravel insert millions of database rows from models

Question

I have a text file that contains comma delineated values representing data set with each row within the string. There are about 2 million of them and I want to parse the string,

Answer 1

I would create an artisan command who handles the import rather than doing this via the browser. Do you like to let the user wait until this big file is imported? What happens if he moves uses the back button or closes the page?

If you want or need to have some kind of user interaction, like the user uploads the file and clicks on an Import button, push the import to a job queue using e.g. Beanstalk. The aforementioned artisan will be run and import the stuff and if its done, you can send the user an e-mail or a slack notification. If you need some UI interaction you can make the request via ajax and that script makes request to an API endpoint requesting the status of the import or since its asynchron, waiting for completion and shows some UI notification, stops a spinner or in error case, shows an error message.
