Locking a Symfony Project to a Specific Major Version of the Framework
======================================================================

[](#locking-a-symfony-project-to-a-specific-major-version-of-the-framework)

Using `symfony/symfony` makes Composer install all Symfony Components, all in the same version. But when using the standalone packages (the Symfony Flex way), Composer might install dependencies in a different major version (`symfony/http-kernel`v2.8 and `symfony/event-dispatcher` v3.4 for instance, usually because another dependency of the project is not compatible with Symfony 3.0).

This Composer package allows you to enforce a consistent major version on all Symfony Components, whether they are explicitly listed as a project's dependency or installed transitively.

For instance when using `dunglas/symfony-lock:^4`, if a package cannot be installed in v4.0, but only in v3.4 (usually because of another library not supporting Symfony 4), a conflict will be generated.

Note that this package is meant to be used by library authors in their continuous integration systems. It should NOT be added directly to the project's `composer.json`.

Difference with `symfony/lts`
-----------------------------

[](#difference-with-symfonylts)

`symfony/lts` enforces that your project don't use use a version not released as a LTS, but does not enforce that all your Symfony packages are in the same major version. For instance, when using `symfony/lts` v3, some packages can be installed in version 3.4, and some others in version 2.8.

Usage
-----

[](#usage)

Use the Composer command line:

```
composer require dunglas/symfony-lock v4
```
