PHP Time Attendance System from Asana?

Question

PHP

We have been using Asana for many years in our team.
The algorithm for working with tasks is as follows:
- the manager sets the task
- the performer completes and writes the time spent, for example: 00:20
- the manager accepts the task and takes into account the time for it in his Excel file for the subsequent calculation of the monthly salary to the executor, and also writes the word: " spent ", which is a signal for the executor to check the task in complete (although sometimes the manager himself does this).
I would like the manager not to deal with this garbage - i.e. entrust this to automation, which will download the mention of time from comments on tasks in the incomplete stage and collect them in its database. And the manager will use this system and, when accepting tasks, check them in this system, which will write for him the word: " carried out " in the task.
Performers will also have access to the system - so that it motivates them to close more tasks per month, because they will understand how much money they have already earned at the moment)
We are going to write the system in PHP - what PHP library would you recommend for this use of the Asana API?
Or maybe something like this already exists and we are inventing a bicycle for our task?
