Guardrails / php

PHP version is declared

php/version-declared@v1

The project declares the PHP version Composer resolves against, and that version is no older than the configured floor.

Id	php/version-declared
Version	v1
Category	php
Default severity	warning
Interpreter	python3
Timeout	30 seconds

Collects	php

Collectors

This guardrail doesn't gather anything itself. It relies on the collectors below, which the CLI runs once per build before any check, and reads what they found from GUARDRAIL_FACTS. If a collector collects nothing, this guardrail is skipped, not failed.

Collector	Gathers	Inputs it is given
php	The Composer project in the project directory: the package it declares, the PHP version and extensions it asks for, the packages it requires and which of them are pinned, and whether the lock file is committed.	projectDir

The inputs above are this guardrail's own inputs, passed straight through to the collector. Setting one in buildnote.json changes what is collected, and two guardrails configured the same way share a single collection.

Configuration

{
  "guardrails": {
      "failOn": "error",
      "checks": [
          {
              "use": "php/version-declared@v1",
              "severity": "warning",
              "with": {
                  "projectDir": ".",
                  "minVersion": "8.1"
              },
              "exemptions": []
          }
      ]
  }
}

Inputs

Input	Description	Default	Environment variable
projectDir	Directory holding the project, relative to the directory the CLI runs in.	.	GUARDRAIL_INPUT_PROJECTDIR
minVersion	Oldest PHP version accepted. A declared version below this is a violation.	8.1	GUARDRAIL_INPUT_MINVERSION

How to fix

Declare the PHP versions the package supports in composer.json:

{
  "require": { "php": ">=8.2" }
}

If you know the deployed runtime, add "config": { "platform": { "php": "8.2.18" } } next to it, because that is the version Composer resolves against. Without either, composer update resolves against whichever PHP the machine running it has. A package that needs a newer runtime than production installs without complaint, and the failure shows up on the first request instead of at install time.

More in php

• php/dependencies-constrained. Every package the manifest requires has a version constraint, instead of accepting whatever the registry serves.
• php/lockfile-committed. The project commits composer.lock, so an install of the same commit resolves the same versions.
