Syntax error with PHP 7.4

Which PHP version are you using?

Content of deploy.php or deploy.yaml

No response

Steps to reproduce

Deployer has been installed relative to the project.

Set the PHP CLI version to 7.4.XX, (7.4.33 has been used.)

composer require  deployer/deployer:7.5.8

vendor/bin/dep deploy stage=STAGE ---branch=main

The deployment fails with the below issue.

Parse error: syntax error, unexpected ')', expecting variable (T_VARIABLE) in phar:///{PATH-TO-PROJECT}/vendor/deployer/deployer/bin/dep/vendor/ringcentral/psr7/src/functions.php on line 355

(A trialling comma in the function arguments, not valid syntax for PHP 7.4)

Am assuming this is because of a composer version bump in ringcentral/psr7 as deployer/deployer:7.5.5 works as expected but I'm struggling to understand how ringcentral/psr7 is required in the Deployer project.

Closed as #3925

I have the same issue here, and I was using version 7.0.0. Upgrading to version 7.5.5 or to 7.5.8 does not solve it.
I think the problem is not in deployer code itself, but in ringcentral/psr7 as @bennoislost suggested.
The crash occurs for me in github runners, so its difficult to see witch version of ringcentral/psr7 is used.

Could you please open the ticket again and provide insights about how ringcentral/psr7 is used by deployer ?

I did more investigations and I'm able to reproduce the problem locally on my computer.
I downloaded the deployer.phar directly from https://deployer.org/download :

$ php deployer-7.5.8.phar deploy preprod -vvv
PHP Parse error:  syntax error, unexpected ')', expecting variable (T_VARIABLE) in phar:///home/vagrant/build/deployer.phar/vendor/ringcentral/psr7/src/functions.php on line 355

$ php deployer-7.0.0.phar deploy preprod -vvv
task deploy:info
[preprod] /usr/bin/php7.4 /home/vagrant/build/deployer-7.0.0.phar worker --port 45243 --task deploy:info --host preprod --decorated -vvv
[preprod] info deploying HEAD
done on preprod

So deployer 7.0.0 was working well. The issue comes from a subsequent version.

[Fab1en]

I found a workaround: to force an old deployer version in the github action setup:
Add deployer-version: 7.0.0 to the deployer-php-action configuration.

      - name: Setup Deployer
        uses: atymic/deployer-php-action@master
        with:
          ssh-private-key: ${{ secrets.SSH_PRIVATE_KEY }}
          ssh-known-hosts: ${{ secrets.SSH_KNOWN_HOSTS }}
          deployer-version: 7.0.0

This is not fixed with #392 since it was introduced in 7.5.6 with commit
44b3a55

7.5.5 is okay:
https://github.com/deployphp/deployer/blob/v7.5.5/vendor/ringcentral/psr7/src/functions.php#L353

7.5.6 not okay:
https://github.com/deployphp/deployer/blob/v7.5.6/vendor/ringcentral/psr7/src/functions.php#L354

This is now resolved as of 7.5.11.
