PHPLint

`phplint` is a tool that can speed up linting of php files by running several lint processes at once.

🚨 There are two better packages for syntax detection and static analysis: Psalm and PHPStan, recently my work has started to get busier and I won't have much time to maintain this project, if you are interested in maintaining it please raise an issue, Thanks.

Installation

Help:
 Lint something

example:

$ ./vendor/bin/phplint ./ --exclude=vendor

You can also define configuration as a file .phplint.yml:

path: ./
jobs: 10
cache: build/phplint.cache
extensions:
  - php
exclude:
  - vendor
warning: false

$ ./vendor/bin/phplint

By default, the command will read configuration from file .phplint.yml of path specified, you can custom the filename by option: --configuration=FILENAME or -c FILENAME;

If you want to disable the config file, you can add option --no-configuration.

Docker cli

docker run --rm -t -v "${PWD}":/workdir overtrue/phplint ./  --exclude=vendor

Please mount the code directory to /workdir in the container.

Program

use Overtrue\PHPLint\Linter;

$path = __DIR__ .'/app';
$exclude = ['vendor'];
$extensions = ['php'];
$warnings = true;

$linter = new Linter($path, $exclude, $extensions, $warnings);

// get errors
$errors = $linter->lint();

//
// [
//    '/path/to/foo.php' => [
//          'error' => "unexpected '$key' (T_VARIABLE)",
//          'line' => 168,
//          'file' => '/path/to/foo.php',
//      ],
//    '/path/to/bar.php' => [
//          'error' => "unexpected 'class' (T_CLASS), expecting ',' or ';'",
//          'line' => 28,
//          'file' => '/path/to/bar.php',
//      ],
// ]

GitHub Actions

uses: overtrue/phplint@8.1
with:
  path: .
  options: --exclude=*.log

Other CI/CD (f.e. Bitbucket Pipelines, GitLab CI)

Run this command using overtrue/phplint:8.1 Docker image:

/root/.composer/vendor/bin/phplint ./ --exclude=vendor

Warnings

Not all linting problems are errors, PHP also has warnings, for example when using a continue statement within a switch case. By default, these errors are not reported, but you can turn this on with the warning cli flag, or by setting the warning to true in the configuration.
