Run PHP scripts with inline dependencies
Execute Composer tools without global installation.
Like
npx
and
uvx
for PHP.
$ brew install
eddmann/tap/phpx
Inline Dependencies
Declare packages in a
// phpx
comment block at the top of your script. They're installed
automatically.
Ephemeral Tools
Run PHPStan, Psalm, PHP-CS-Fixer, and more without polluting your global environment. Tools are cached for fast re-runs.
Automatic PHP Management
Downloads pre-built static PHP binaries matching your version constraints. No system PHP required.
Smart Caching
PHP binaries, dependencies, and tools are intelligently cached
at
~/.phpx/
for instant subsequent runs.
Secure by Design
Run untrusted scripts safely with built-in sandboxing. Control filesystem access, network, and resource limits.
Filesystem Isolation
Restrict access to only what scripts need
Network Control
Block network or allow specific hosts
Resource Limits
Control memory, CPU, and execution time
Uses sandbox-exec on macOS, bubblewrap on Linux
Quick Start
Add a comment block to declare dependencies, then run your script.
