Question

We make usage of Guzzle HTTP in order to make HTTP(s) request in order to generate a CSV file; Another component that we use is the $_SESSION variable to store status information about the generation of the different files.

The main problem with this approach is that PHP blocks all other requests that make usage of the $_SESSION variable. We know that we can defeat this "problem" with a certain function that is called session_write_close();

But we still need to be able to update the information and store it in the $_SESSION variable later on and we should also be able to use the $_SESSION information in other sections of the site; Thus it should be "synced".

Sadly session_write_close is exactly what you would need to use in order to make sure the request is not blocking. My suggestion is to get and set all the session information you need at the start of the script, before you start to generate your CSV. Then call session_write_close and continue with creating your CSV file.
