Composer

The require command adds new packages to the composer.json file. A composer.json file will be created if one doesn’t exist. After adding/changing the requirements, the modified requirements will be installed or updated.

Options:

  • --update-with-dependencies (-w): Also update dependencies of the newly required packages, except those that are root requirements.
  • --update-with-all-dependencies (-W): Also update dependencies of the newly required packages, including those that are root requirements.
