phpvm (PHP Version Manager)
Lightweight command-line PHP runtime switcher for Windows developers
Core Features Implemented
- Instant CLI Runtime Switching: One-command switching between PHP 7.4, 8.0, 8.1, 8.2, and 8.3 with zero OS reboots or manual PATH editing
- Atomic Symlink Proxy: Dynamically updates a single shim directory in the system PATH to point to selected PHP installations safely
- Extension Compatibility Checker: Automatically verifies and enables matching extensions (curl, pdo_mysql, mbstring) across active runtimes
- Windows Registry Integrity Guard: Non-destructive environment modification preventing duplicate PATH pollution or corrupted keys
System Architecture
- Atomic Windows directory junction/symlink replacement avoiding shell reboot requirements
- Automated php.ini extension directory resolution matching VC runtime compilers
- SHA256 checksum verification validating downloaded Windows PHP zip archives from official sources
- Compact standalone script package (< 1.5MB) with zero third-party framework dependencies
