Add composer for cPanel user Print

Option 1 — Install Composer inside CageFS for all users

1. As root, run:

   bash

   /usr/bin/selectorctl -V

   Make sure 8.3 is available.

2. Add Composer to CageFS’ skeleton:

   bash

   wget https://getcomposer.org/composer-stable.phar -O /usr/share/cagefs-skeleton/usr/local/bin/composer

   chmod +x /usr/share/cagefs-skeleton/usr/local/bin/composer

   Then update CageFS for all users:

   bash

   cagefsctl --force-update

3. Now log in as the cPanel user and run:

   bash

   composer --version

   php -v

   Make sure php points to CloudLinux’s alt-php83.
