Package Manager

zphp includes a package manager that uses Packagist, the same registry that Composer uses. It is not a complete replacement for Composer. Test installed packages with your application.

Quick start

$ zphp add slim/slim

This creates a composer.json, resolves dependencies, downloads packages, and generates a vendor/autoload.php that works with zphp's autoloader.

Commands

Command	Description
`zphp install`	Install all packages from `composer.json`
`zphp add <package>`	Add a package and install it
`zphp remove <package>`	Remove a package
`zphp packages`	List installed packages

composer.json

zphp reads require, require-dev, and project PSR-4 mappings from composer.json:

{
    "require": {
        "slim/slim": "^4.0",
        "slim/psr7": "^1.0"
    },
    "autoload": {
        "psr-4": {
            "App\\": "src/"
        }
    }
}

Version constraints

Constraint	Meaning
`^1.2.3`	>=1.2.3, <2.0.0
`~1.2.3`	>=1.2.3, <1.3.0
`>=1.0`	1.0 or higher
`*`	Any version
`1.2.3`	Exact version

zphp install writes resolved versions to zphp.lock, but resolves dependencies again on each install rather than installing from that lock file. It does not provide Composer-style reproducible installs.

The resolver skips php and ext-* requirements. Composer scripts, plugins, and the full Composer dependency-resolution behavior are not implemented. Keep using Composer when your project depends on those features.

Autoloading

The generated vendor/autoload.php supports project and package PSR-4 mappings and package autoload.files entries. It does not implement every Composer autoload mode.

<?php
require __DIR__ . '/vendor/autoload.php';
