Thank you very much for the explanation, it helped a lot.

Hi, Can you please help with using this on a beanstalk app with php 7.1? It looks like this is for php5. What all should I change to meet with the latest aws beanstalk php 7.1?

Hi, Can you please help with using this and customization need to adjust deploy this code on EBS with PHP7.2 in Amazon linux version 2(latest). This code will work only for AWS linux version 1.

Since In AWS linux 2 folder structure got changed and the below listed folders are not available in aws linux2.

hooks/configdeploy/enact

Below will be latest folder structure and trying to change this code to new hook
