Questions tagged [composer-php]

Composer is an application-level package manager for the PHP programming language. It provides a standard format for managing with ease PHP-based project dependencies (libraries) and was strongly inspired by Node.js's "npm" and Ruby's "bundler". Use with the [php] tag

Presentation

Composer is an application-level package manager.

Yes, it deals with "packages" or libraries, but it manages them on a per-project basis, installing them inside your project's directory.

By default, it will never install anything globally.

Thus, it is considered a PHP-based project package manager.

Useful links

It aggregates all sorts of PHP packages that are installable with Composer.

Also, you can check your build log; it could be helpful for debugging.
