Static PHP: It's Not What You Think

First, let's clear up a common point of confusion. When developers hear "Static PHP," they often think of static analysis tools like PHPStan or Psalm. These excellent tools analyze your code for bugs and quality issues without running it. However, static-php-cli serves a completely different purpose. It's not about analyzing code; it's about static compilation—or more precisely, static linking.

The main idea is to bundle the PHP interpreter, your chosen extensions, and even your application's source code into a single, standalone executable file. No external PHP installation required.

The Anatomy of a Statically Compiled Binary

The static-php-cli builder is a sophisticated tool that produces two distinct types of artifacts to suit different needs.

Static CLI/FPM Binary

This is a complete, portable PHP interpreter. You can build a php-cli or php-fpm binary with all your required extensions compiled directly into it. This is perfect for creating consistent CI/CD pipelines or ultra-lightweight Docker images.

phpmicro Self-Extracting Executable

This is where the magic happens for application distribution. This feature packages the static PHP runtime and your application's source code (often as a PHAR file) into one single executable file. This is the key to creating zero-dependency, single-file applications in PHP.

Use Case #1: Zero-Dependency CLI Tools That Run Anywhere

The most immediate and powerful use case for static-php-cli is creating command-line applications that are truly portable. A developer can build a tool and distribute it as a single file that end-users can run without installing PHP or any extensions.

The perfect example is compiling an application built with Laravel Zero, a micro-framework for console apps. While you can package a Laravel Zero app as a PHAR archive, that archive still requires a PHP installation on the host machine. static-php-cli solves this "last mile" problem by embedding the PHAR and the runtime into a single executable, finally achieving the "run anywhere" goal.

Use Case #2: Powering the Next Generation of PHP Frameworks

This technology is so foundational that it's enabling other groundbreaking projects to emerge.

Use Case #3: Revolutionizing PHP in DevOps and the Cloud

For DevOps engineers, static-php-cli is a game-changer for containerization. A fully static binary can run from a scratch Docker image—an empty image with no operating system layer. This leads to profound benefits:

• Drastically Reduced Image Size: From 200MB+ to well under 10MB.
• Hardened Security: Reduced attack surface with no OS layer.
• CI/CD Efficiency: Faster push and pull times for images.

The Catch: What Are the Trade-Offs?

This powerful new capability isn't without its costs. The complexity has shifted from runtime to build time.

• Binary Size: Grows with each added extension.
• Cross-Compilation is Difficult: Generally requires building on the target OS and architecture.
• Build Times and Environment Fragility: Can be slow and complex.

Final Analysis: Who Should Adopt Static Compilation?

static-php-cli represents a strategic evolution in the PHP ecosystem, trading development-time simplicity for deployment-time reliability and performance.
