- How do I install sixlive/dotenv-editor in a Laravel project?
- Install it with Composer using composer require sixlive/dotenv-editor. In Laravel, you can pair it with the sixlive/laravel-dotenv-editor wrapper or register a small service provider manually if you prefer to inject it. The core library is framework-agnostic, so the same API works in plain PHP applications.
- Does sixlive/dotenv-editor preserve comments and key order when editing .env?
- The package is described as preserving comments, formatting, and key order during round-trips. That is the intended behavior, but .env files vary widely in quoting, blank lines, and inline comments, so test it against your real files before relying on byte-for-byte fidelity. Keep a backup and compare the output for any unusual .env shape you support.
- Which PHP and Laravel versions does sixlive/dotenv-editor support?
- The exact PHP and Laravel version constraints are not stated in the provided overview, so check the package's composer.json for the PHP requirement. If you use the Laravel wrapper, check that package's composer.json separately for its Laravel framework constraints. The core library has no framework coupling, so its PHP constraint is the main compatibility gate.
- How do I update an existing .env variable without duplicating the key?
- Load the file, call the update path for an existing key, then save. The public API exposes load(), addKey(), updateKey(), deleteKey(), setKey(), and save(), so use updateKey() or setKey() for existing entries and addKey() for new ones. Check the source or tests to confirm whether updateKey() fails or creates a key when the entry is absent.
- Is sixlive/dotenv-editor safe to use in production for admin settings screens?
- It is a reasonable fit for human-initiated, low-frequency writes such as installers, artisan commands, and admin screens that set mail, queue, or API credentials. Treat production use as needing safeguards you add around it: backup before write, atomic replace, permission checks, value validation, and a service-layer wrapper. Remember that Laravel reads .env at bootstrap, so changes apply on the next process boot, and cached config must be cleared.
- How does sixlive/dotenv-editor handle values with spaces, quotes, #, or $ characters?
- The provided context does not document quoting or escaping behavior for complex values. Because .env is not a formally specified format, test values containing spaces, #, =, newlines, dollar signs, and escaped quotes explicitly. If fidelity is critical, validate and restrict values before saving, and verify the output with the same dotenv parser your application uses.
- Does save() write .env atomically, and does it lock the file for concurrent writes?
- Atomic write behavior and file locking are not stated in the provided documentation. Do not assume save() uses a temp-file-plus-rename strategy or guards against concurrent writers. If multiple requests or hosts can write the file, add your own locking, atomic replace, and backup strategy around the package.
- What happens if the .env file is missing or read-only with sixlive/dotenv-editor?
- The overview does not specify whether missing or read-only files produce typed exceptions or silent failures. Check is_readable() and is_writable() before calling save(), wrap calls in try/catch, and surface a clear error to the caller. Test this in containerized or read-only filesystem environments, because permission failures are a common production surprise.
- What are alternatives to sixlive/dotenv-editor for editing env files in PHP?
- vlucas/phpdotenv is the standard reader for .env files but is not primarily an editor, so many teams pair it with custom write logic. Other options include a small custom parser that you control, generating .env from a template plus validated settings, or framework-specific configuration commands. Choose based on how much round-trip fidelity and concurrency safety you need.
- Is sixlive/dotenv-editor actively maintained and well tested?
- The package has a recent release date of 2025-09-08, which is a positive activity signal, but roughly 74 stars suggests a small user base and a thin maintainer bench. Test coverage and fixtures for pathological .env files are not described in the provided context, so inspect the repository and tests before adopting it. Pin the version and review the source if long-term maintenance is a concern.
