Transfer big data to php server-script

Question

Currently I´m creating a little IDE in Javascript on my webpage and I´m struggling at the concept of the saving process. For the beginning I want to save the whole code written in my IDE to be saved in a .txt .

So far I know how to pass values from client-JS to server-PHP with HTTP-request, but my case I basically have to transfer a very long string. From within the php script I want to create/manipulate a .txt to save the data outside of the root of the webserver.

So I was wondering if there is a good solution to pass a lot of data at once to my php running on the server.
