Can I use Composer for my PHP project?

Composer can basically be used, but it is not directly available as a global command via SSH.

Instead, usage is done through the file composer.phar provided by Composer.

For more information, see here: How do I connect to my webspace via SSH?

Installing composer.phar

First, connect to your webspace via SSH and switch to your project directory.

Then follow the installation steps from the official Composer website: https://getcomposer.org/download/

After installation, the file composer.phar will be in your project directory.

Using Composer

Since Composer is not available globally, the composer.phar file must be executed via PHP.

Example:

Standard command:

composer require symfony/dotenv

Adjusted command:

php composer.phar require symfony/dotenv

If you want to use a specific PHP version, you can specify it directly:

php8.2 composer.phar require symfony/dotenv
