[Howto]: Configure different PHP version for separate projects

[cw95403]

Have you already checked elsewhere?

• I have read the Devilbox documentation
• I have checked the Devilbox Troubleshooting Guide
• I have checked the Devilbox FAQ

• I have checked the Devilbox Forum

• I have not done any of the above

What are you struggling with?

I am working on getting different versions of PHP running with different projects.

The error I am getting is the following when attempting to access a project that uses other than the default version of PHP:

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

I am on an M1 Mac with:
Devilbox v3.0.0-beta-0.3 (2023-01-02)

I have run through the configuration instructions on #942

docker-compose.override.yml is active
PHP56 and PHP81 are loaded. PHP81 is the system default
backend.cfg consists of: conf:phpfpm:tcp:php56.local:9000

The Devilbox virtual hosts page displays the following in the backend column: tcp://php56.local:9000

Any suggestions on how to get it working would be much appreciated.

What have you tried already?

Run through available documentation, validate configurations. Validate proper containers are running. Shelling into running containers.

What is your goal?

Use different versions of PHP on different projects.
