How to change the root directory for php scripts?

Question

PHP

Good day.
There is a small site in PHP (OS - Ubuntu Server, Apache 2.4).
When executing a command from any script, php gives a list of all root folders (root, var, home, etc.) How can I make php consider the folder that I specify as the root?
scandir('/');

Answer 1

chroot
php.net/manual/ru/ini.core.php#ini.open-basedir

Answer 2

First, make sure it sees all files. Write right after src:
gulp.src(scriptPaths)
.on('data', function(file){ console.log(file);})
.pipe(concat('script.js'))
Try removing gulp-concat and put on a new one.
