When you install php components using composer, you will find that a composer.lock file has been created. What does this do?

Composer.lock is a record of all currently installed versions of php components, if multi-person collaborative development needs to maintain the downloaded version of php components to reduce unnecessary trouble, then you need to add composer.lock to version control, such as using git or svn, then you need to add it to version control. On the contrary, it is not necessary.

It is important to note that when composer install makes component dependencies, the composer.lock file will not be updated unless a new component is introduced into composer.json, if you want to update, use composer update to update the component to the latest stable version and update the composer.lock file.
