How to install composer on php hosting?

Question

PHP

I saw instructions for the Linux machine itself through the terminal, but I need to upload it to the hosting.

Answer 1

You can download composer.phar and run it without installation.
To start, you need to go to the folder where composer.phar is located and then execute
/ update commands, etc.

If composer, then write to the hosting administrators, you can try via SSH if available.
