docker-compose not working in php script?

Question

PHP

Even ashamed to write this topic.
The fact is that docker-compose does not work in a php script.
There are no errors.

The user from which the php script is launched is a member of the docker group.
Even docker-compose --version doesn't work

<?php

set_time_limit(3600);

$old_path = getcwd();

// Pull project
echo shell_exec("git pull origin develop");
chdir('/var/www/epsyteam/data/epsy-api/');
echo shell_exec("docker-compose up -d --build --remove-orphans");

What could be the problem?

Answer 1

most likely on the way.
