Dependencies with extensions from PECL, PEAR, Composer

I guess most people will agree.
Often a PHP Class / project depends on something else from pecl, pear,composer or github. Or it requires an external database.

There is the function
Add a new dependency for a class
phpclasses.org/add_dependency.html

How about, we are able to describe dependencies with other stuff in more detail.
Perhaps a small table: Source, Key, Value
e.g.
Source=pecl
Key=ds
Value= bla bla https://www.php.net/manual/en/ds.installation.php

Source=composer
Key=php-ds/php-ds
Value=bla bla https://packagist.org/packages/php-ds/php-ds

Where value may contain an URL to a known source

Hello Matt,

Nowadays many people use composer to express specific dependencies.

If you install a package from the PHP Classes site using composer, even when you do not user composer in your projects, the PHP Classes site will serve a composer.json file to composer, so it can install the package and any dependency packages.
