PHP 8.4 Deprecation: ${var} string interpolation syntax needs to be updated to {$var}

[connecteev]

Hello! I'm using ta-tikoma/phpunit-architecture-test version 0.8.5 and encountering a deprecation warning when running tests:

Using ${var} in strings is deprecated, use {$var} instead // vendor/ta-tikoma/phpun…

Context:
PHP Version: 8.4
Package Version: 0.8.5
This deprecation was introduced in PHP 8.2 and will become a fatal error in PHP 9.0

Issue:
The old string interpolation syntax "${var}" is deprecated and should be changed to "{$var}" throughout the codebase.
Example of what needs to be changed:
php// ❌ Deprecated (PHP 8.2+)
$message = "Value: ${variable}";

// ✅ Correct
$message = "Value: {$variable}";

Impact:
This causes deprecation warnings in test output and will break when PHP 9.0 is released.

Test Code:

    // Broad namespace test
    it('confirms die, dd, dump not used in App namespace')
        ->arch()
        ->expect('App')
        ->not->toUse(['die', 'dd', 'dump']);

Error:

Request:
Could you please update all instances of ${var} to {$var} in the package? This should be a simple find-and-replace operation across the source files.
Thank you for maintaining this package!

But I will try to install laravel on php 8.4 image and repeat test.

I ended up here because I also saw this message and was wondering why this library was throwing it. What I discovered was that even though the message lists this project, the problem was actually in my own code and not in this project at all. There was a spot that I had done print "${var}" and using the arch()->preset()->php() rule in my tests triggered this message.
