Add flag parsing in `install_php()` +2. Add post-install alias setting +3. Add post-install .phpvmrc writing +4. Add confirmation prompts +5. Add silent mode support + +--- + +### 6. Enhanced Use Options (MEDIUM PRIORITY) + +**Current State:** `phpvm use` accepts only version number. + +**NVM Implementation:** +- `--silent`: Suppress output +- `--save`: Write to .nvmrc +- `--lts`, `--lts=`: Use LTS versions + +**Proposed PHPVM Implementation:** +```bash +# Enhanced use command +phpvm use [flags] + +# Flags to implement +--silent # Suppress output +--save # Write to .phpvmrc in current directory + +# Examples +phpvm use 8.2 --save +phpvm use default --silent +phpvm use production --save +``` + +--- + +### 7. Version Resolution (MEDIUM PRIORITY) + +**Current State:** phpvm requires exact version numbers. + +**NVM Implementation:** +- `nvm version `: Resolve locally +- `nvm version-remote `: Resolve remotely +- Supports patterns like "8", "8.x", "lts/*" + +**Proposed PHPVM Implementation:** +```bash +# Commands to implement +phpvm version # Resolve pattern to installed version +phpvm version-remote # Resolve pattern to remote version + +# Pattern support +phpvm version 8 # Returns latest 8.x.x installed +phpvm version 8.2 # Returns latest 8.2.x installed +phpvm version latest # Returns latest installed version +phpvm version stable # Returns latest stable version + +# Examples +$ phpvm version 8 +8.3.1 +$ phpvm version-remote 8.2 +8.2.15 +``` + +--- + +### 8. Package/Extension Migration (MEDIUM PRIORITY) + +**Current State:** No extension migration support. + +**NVM Implementation:** +- `nvm reinstall-packages `: Copies global npm packages + +**Proposed PHPVM Implementation:** +```bash +# Command to implement +phpvm reinstall-packages # Migrate extensions to current version +phpvm reinstall-packages # Migrate between specific versions + +# Example +phpvm use 8.2 +phpvm reinstall-packages 8.1 # Copy extensions from 8.1 to 8.2 +``` + +**Implementation Challenges:** +- PHP extensions are compiled per version +- Package manager differences (pecl vs apt-get) +- Extension compatibility varies by PHP version +- May require recompilation + +**Possible Approach:** +1. List extensions from source version: `php -m` +2. Filter to installed extensions (exclude bundled) +3. Attempt to install each in target version +4. Report success/failure for each extension + +--- + +### 9. Unload Command (MEDIUM PRIORITY) + +**Current State:** phpvm has `deactivate` but not full unload. + +**NVM Implementation:** +- `nvm unload`: Removes all nvm functions from shell +- More complete than deactivate + +**Proposed PHPVM Implementation:** +```bash +# Command to implement +phpvm unload # Completely unload phpvm from shell + +# What it should do: +1. Remove all phpvm functions from shell +2. Restore original PATH +3. Unset all PHPVM_* environment variables +4. Remove phpvm command from shell +``` + +--- + +### 10.

All tests pass on supported platforms +5. Documentation is complete and accurate +6. Performance is acceptable (no significant slowdown) +7. User feedback is positive + +## Notes and Caveats + +### PHP vs Node.js Differences +- **No LTS concept**: PHP doesn't have official LTS versions like Node.js +- **Package managers**: PHP relies on system package managers (apt, brew, etc.) while nvm downloads binaries +- **Extensions**: PHP has compiled extensions (C modules) vs npm packages (JavaScript) +- **Compilation**: nvm can compile from source; phpvm uses pre-built packages + +### Package Manager Limitations +- **apt/yum/dnf**: Version availability depends on repository configuration +- **Homebrew**: Limited to versions in Homebrew formulae +- **pacman**: Arch Linux typically has only current version +- Some features (like binary caching) may not apply + +### Implementation Considerations +- Maintain cross-platform compatibility (macOS, Linux, WSL) +- Keep script size manageable (currently ~2300 lines) +- Preserve excellent error handling +- Maintain security standards +- Keep installation simple + +## Conclusion + +This analysis identifies 15+ major features missing from phpvm that exist in nvm. Implementing these features in priority order will bring phpvm to full feature parity with nvm, making it the most comprehensive PHP version manager available. + +**Estimated Total Effort:** 10-12 weeks for full implementation +**Lines of Code to Add:** Approximately 1500-2000 lines +**Testing Effort:** 2-3 weeks +**Documentation Effort:** 1 week + +--- + +**Document Version:** 1.0 +**Last Updated:** 2026-01-04 +**Prepared by:** GitHub Copilot Analysis +**For:** phpvm Project Enhancement From f36c83a8670f6a042b91ca927d78a5a501b25842 Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Sun, 4 Jan 2026 07:34:04 +0000 Subject: [PATCH 3/4] Add feature parity checklist for quick reference Co-authored-by: Thavarshan <10804999+Thavarshan@users.noreply.github.com> --- FEATURE_CHECKLIST.md | 178 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 178 insertions(+) create mode 100644 FEATURE_CHECKLIST.md diff --git a/FEATURE_CHECKLIST.md b/FEATURE_CHECKLIST.md new file mode 100644 index 0000000..96c4125 --- /dev/null +++ b/FEATURE_CHECKLIST.md @@ -0,0 +1,178 @@ +# phpvm Feature Parity Checklist + +A quick reference checklist of features needed to achieve full functional parity with nvm. + +## ✅ Already Implemented (Compatible with NVM) + +- [x] `phpvm install ` -
