### Installing PHP packages with extensions {#ssec-php-user-guide-installing-packages-with-extensions}
All interactive tools use the PHP package you get them from, so all
packages at `php.packages.*` use the `php` package with its default
extensions. Sometimes this default set of extensions isn't enough and
you may want to extend it. A common case of this is the `composer`
package: a project may depend on certain extensions and `composer`
won't work with that project unless those extensions are loaded.
Example of building `composer` with additional extensions:
```nix
(php.withExtensions ({ all, enabled }:
enabled ++ (with all; [ imagick redis ]))
).packages.composer
```
