static-php-build 0.1.5

Independent build tool producing a host PHP binary via static-php-cli

static-php-build

Bake the PHP extensions you need into a portable host binary, once, at packaging time.

Produce a host PHP binary loading a required extension set by driving static-php-cli (spc).

Install

pip install static-php-build

A build-time / development dependency, not a runtime dependency of a consumer's end users. spc compilers are bundled per host platform; hosts without a bundled spc supply one via --spc PATH.

Usage

# Build a host PHP binary loading the given extensions, write it to ./php
static-php-build --extensions tokenizer,mbstring --out ./php

# Read the required set from the consumer's requirement declaration instead
static-php-build --manifest your_lib:REQUIREMENTS --out ./php

# Pin the PHP version, and forward unmodeled spc options after the `--` separator
static-php-build --extensions tokenizer --out ./php --with-php 8.4 -- --enable-zts

# Use an explicit spc on a host without a bundled one
static-php-build --extensions tokenizer --spc /path/to/spc --out ./php

from static_php_build import BuildRequest, build

report = build(BuildRequest(extensions=["tokenizer", "mbstring"], out="./php"))
print(report.satisfied, report.missing)

Each invocation builds for the host it runs on, so cross-OS coverage means one CI job per OS. A minimal GitHub Actions matrix:

jobs:
  build-php:
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
    runs-on: ${{ matrix.os }}
    steps:
      - run: pipx run static-php-build --extensions tokenizer,mbstring --with-php 8.4 --out dist/php
      - uses: actions/upload-artifact@v4
        with:
          name: php-${{ matrix.os }}
          path: dist/php*

The tool verifies each produced binary via its own php -m read; a non-CLI artifact fails verification and raises. The handoff to static-php-py is the produced binary on disk, loaded at runtime through PHP.local. Full workflow (bundling the artifacts into per-OS wheels): ../../docs/llms/bundling-pipeline.md.

API

Command

static-php-build (--extensions NAMES | --manifest MODULE:ATTR) [--out PATH] [--spc PATH] [--with-php VERSION] [-- <spc args>]

• --extensions — the required set as comma-separated extension names.
• --manifest — MODULE:ATTR naming an importable object exposing extensions (a consumer's Requirements constant); exactly one of --extensions and --manifest is required.
• --out — file path receives the binary; directory path receives php/php.exe inside it. Omitted: ./php (./php.exe on Windows).
• --spc — explicit spc binary; supersedes the bundled spc for the run.
• --with-php — major.minor PHP version pinned on spc's download step. Omitted: spc default.
• -- <spc args> — forwarded to spc's build step verbatim; the tool's own flags are never forwarded.
• Exit codes: 0 success, 1 runtime failure (BuildError), 2 misuse (no extension set resolvable).

Function

build(request: BuildRequest | None = None) -> ExtensionReport

Produces a host binary loading the required extensions, verifies it, writes it to the destination, and returns the report.

• BuildRequest — frozen data holder grouping the build inputs: extensions, manifest, out, spc, php_version, spc_args, timeout. Exactly one of extensions and manifest names the required set.
• ExtensionReport — frozen data holder: required, loaded, missing, satisfied.

Exceptions

• BuildError — base (distinct from static-php-py's PHPError).
• ProvisioningError — spc download/build failed, output binary absent, or a required extension is missing.
• UnsupportedHostError — no bundled spc for the host and no --spc supplied; names --spc as the remedy.
