Switch PHP version under Homestead

Laravel’s Homestead comes with PHP5.6, PHP7.0, and PHP7.1 and PHP7.2 these 4 versions. By default it runs up to version 7.2, but sometimes company needs have to switch to another version.

How to switch?

Homestead comes with a way to switch versions, as follows:

sites:
    - map: homestead.test
      to: /home/vagrant/code/Laravel/public
      php: "5.6"

However, when you execute composer in homestead, or use php -v When checking the php version, the highest version is still 7.2. As a result, when composer performs a version check or updates the package, it will be updated according to version 7.2.

How to do it?

homestead comes with version management toolsupdate-alternatives

The usage is as follows:

update-alternatives --display php 查看所有 php 版本和当前版本
update-alternatives --config php 执行后，会列出当前 php 所有版本和编号，输入编号，切换到执行的版本

I didn’t notice that there is a file in the Homestead directory before aliases file, this file defines some commands that can be used directly in the virtual machine. For example, if you want to switch to version 7.0, just execute

php70
