7To5 Laravel Package
spatie/7to5
Abandoned. Converts PHP 7.0 code to PHP 5, useful when developing on PHP 7 but deploying to PHP 5. Provides a CLI to convert entire directories and rewrites features like anonymous classes, type hints, return types, and null coalescing.
Convert PHP 7 code to PHP 5 code
Frequently asked questions about 7To5
- Can spatie/7to5 convert Laravel 5.5+ code to PHP 5 for deployment?
- No. Laravel 5.5+ dropped PHP 5.x support entirely, so this package won’t work unless you’re maintaining a parallel branch for Laravel ≤5.4. Even then, framework-specific syntax (e.g., Blade, Eloquent) may break.
- How do I install spatie/7to5 for directory conversion?
- Run `composer global require spatie/7to5` for global CLI access, then use `php7to5 convert <source> <destination>` to rewrite files. For project-specific use, add it to `require-dev` in `composer.json` and run via `./vendor/bin/7to5`.
- Does this tool handle Laravel’s Blade templates or collect() methods?
- No. Blade directives (e.g., `@php`) and Laravel’s fluent methods (e.g., `collect()->where()`) aren’t automatically converted. Manual fixes or exclusion from conversion are required.
- What PHP 7 features does spatie/7to5 NOT support?
- It skips complex constructs like `match` expressions, `foreach` with references, `array`/`object` destructuring, and dynamic code (e.g., `eval()`, `create_function()`). These will cause errors or require manual rewrites.
- How can I test converted code for PHP 5 compatibility?
- Run `php -l` on converted files for syntax errors, then test with PHP 5.6’s error reporting: `php -d error_reporting=E_ALL script.php`. Use PHPUnit 5.x for unit tests, but expect false positives in edge cases.
- Is spatie/7to5 safe for production use? What risks exist?
- No. The package is abandoned (last update: 2018) and may introduce logical errors (e.g., scope changes, performance regressions). Always review converted code manually and avoid converting third-party libraries.
- Can I integrate this into a CI pipeline for automated PHP 5 checks?
- Yes, but with caveats. Add a step like `./vendor/bin/7to5 --dry-run src/ && php -l converted_files/` to validate syntax. Disable it for Laravel 6+ projects or modern PHP stacks.
- What are modern alternatives to spatie/7to5 for PHP 5 migration?
- Consider `php-cs-fixer` with custom rules for syntax fixes, or Dockerize PHP 5.x for isolated legacy testing. For full migration, plan a phased upgrade to PHP 7.4+ (Laravel 8+) with feature flags.
- How do I handle anonymous classes converted to named classes like `AnonymousClass0`?
- The tool auto-generates unique class names, but this can cause collisions if the same anonymous class appears multiple times. Review converted files to rename classes manually or extend the tool’s logic.
- Will this break Laravel’s service providers or Facades after conversion?
- Likely. Service providers using PHP 7+ syntax (e.g., type-hinted bindings) or Facades relying on late static binding may fail. Test thoroughly and consider rewriting providers in PHP 5-compatible syntax.
