Version Laravel Package

phar-io/version

phar-io/version is a PHP library for parsing, comparing, and validating semantic versions and version constraints. Supports operators like >=, <=, caret (^) and tilde (~) ranges, plus pre-release labels, to check if versions comply.

Product Decisions This Supports

  • Enables robust version constraint validation for plugin ecosystems, dependency resolution, and environment compatibility checks (e.g., ensuring PHP extensions meet required versions)
  • Critical for SaaS platforms managing third-party integrations where precise version compatibility is non-negotiable (e.g., "Plugin X requires ^7.0 || ^8.0")
  • Eliminates reinventing version parsing logic – avoids custom implementations prone to edge-case failures (e.g., pre-release handling, build metadata)
  • Supports build-vs-buy decisions by providing a battle-tested solution with 7k+ stars and active maintenance, reducing technical debt vs. homegrown alternatives
  • Use cases: CLI tool version requirements, package manager compatibility checks, release pipelines enforcing semantic versioning rules

When to Consider This Package

  • Adopt when building PHP applications needing semver-compliant version parsing, especially with pre-release tags (alpha/beta), build metadata, or complex constraints (e.g., ^1.2 || ~3.0)
  • Ideal for Composer-based projects requiring precise dependency version validation (e.g., plugin architectures, framework extensions)
  • Look elsewhere if: your project uses non-PHP stacks, requires non-semver versioning schemes (e.g., date-based or custom formats), or only needs trivial version checks (e.g., simple major version comparison)
  • Avoid if maintenance cadence is critical – while actively maintained (last release 2022-02-21 with recent patches), check GitHub activity for your specific needs

How to Pitch It (Stakeholders)

Executives: "This package eliminates version-related bugs and reduces development costs by providing a proven solution for dependency compatibility checks. It ensures seamless integration between components, minimizes support tickets from version mismatches, and accelerates feature delivery by leveraging a trusted, open-source tool used across high-impact PHP projects."
Engineering: "A lightweight, rigorously tested library that handles all semver edge cases – including pre-release suffixes, build metadata, and complex constraint parsing (e.g., ^0.3 or ~1.2|>2.0). Integrates in minutes via Composer with zero configuration, and has been battle-tested in production for years with full PHP 7.2+/8.0 support."
