A set of custom fixers for PHP CS Fixer.

Installation

PHP CS Fixer: custom fixers can be installed by running:

composer require --dev kubawerlos/php-cs-fixer-custom-fixers

Usage

In your PHP CS Fixer configuration register fixers and use them:

 <?php
 return (new PhpCsFixer\Config())
+    ->registerCustomFixers(new PhpCsFixerCustomFixers\Fixers())
     ->setRules([
         '@PSR2' => true,
         'array_syntax' => ['syntax' => 'short'],
+        PhpCsFixerCustomFixers\Fixer\NoLeadingSlashInGlobalNamespaceFixer::name() => true,
+        PhpCsFixerCustomFixers\Fixer\PhpdocNoSuperfluousParamFixer::name() => true,
     ]);

⚠️ When PHP CS Fixer is installed via php-cs-fixer/shim package, requiring bootstrap may be needed to load PhpCsFixerCustomFixers classes:

require __DIR__ . '/vendor/kubawerlos/php-cs-fixer-custom-fixers/bootstrap.php';

Fixers

CommentSurroundedBySpacesFixer

Comments must be surrounded by spaces.

 <?php
-/*foo*/
+/* foo */

CommentedOutFunctionFixer

The configured functions must be commented out. Risky: when any of the configured functions have side effects or are overwritten. Configuration options:

  • functions (array): list of functions to comment out; defaults to ['print_r', 'var_dump', 'var_export']
 <?php
-var_dump($x);
+//var_dump($x);

ConstructorEmptyBracesFixer

Constructor's empty braces must be single line.

 <?php
 class Foo {
     public function __construct(
         $param1,
         $param2
-    ) {
-    }
+    ) {}
 }

DataProviderNameFixer

Data provider names must match the name of the test. DEPRECATED: use php_unit_data_provider_name instead. Risky: when relying on name of data provider function. Configuration options:

  • prefix (string): prefix that replaces "test"; defaults to 'provide'
  • suffix (string): suffix to be added at the end"; defaults to 'Cases'
 <?php
 class FooTest extends TestCase {
     /**
-     * @dataProvider dataProvider
+     * @dataProvider provideSomethingCases
      */
     public function testSomething($expected, $actual) {}
-    public function dataProvider() {}
+    public function provideSomethingCases() {}
 }

DataProviderReturnTypeFixer

The return type of PHPUnit data provider must be iterable. DEPRECATED: use php_unit_data_provider_return_type instead. Risky: when relying on signature of data provider.

 <?php
 class FooTest extends TestCase {
     /**
      * @dataProvider provideSomethingCases
      */
     public function testSomething($expected, $actual) {}
-    public function provideSomethingCases(): array {}
+    public function provideSomethingCases(): iterable {}
 }

DataProviderStaticFixer

Data providers must be static. DEPRECATED: use php_unit_data_provider_static instead. Risky: when force is set to true. Configuration options:

  • force (bool): whether to make static data providers having dynamic class calls; defaults to false
 <?php
 class FooTest extends TestCase {
     /**
      * @dataProvider provideSomethingCases
      */
     public function testSomething($expected, $actual) {}
-    public function provideSomethingCases() {}
+    public static function provideSomethingCases() {}
 }

DeclareAfterOpeningTagFixer

Declare statement for strict types must be placed in the same line, after opening tag.

-<?php
+<?php declare(strict_types=1);
 $foo;
-declare(strict_types=1);
 $bar;

EmptyFunctionBodyFixer

Empty function body must be abbreviated as {} and placed on the same line as the previous symbol, separated by a space.

 <?php function foo(
     int $x
-)
-{
-}
+) {}

InternalClassCasingFixer

Classes defined internally by extension or core must be referenced with the correct case. DEPRECATED: use class_reference_name_casing instead.

 <?php
-$foo = new STDClass();
+$foo = new stdClass();

IssetToArrayKeyExistsFixer

Function array_key_exists must be used over isset when possible. Risky: when array is not defined, is multi-dimensional or behaviour is relying on the null value.

 <?php
-if (isset($array[$key])) {
+if (array_key_exists($key, $array)) {
     echo $array[$key];
 }

MultilineCommentOpeningClosingAloneFixer

Multiline comments or PHPDocs must contain an opening and closing line with no additional content.

 <?php
-/** Hello
+/**
+ * Hello
  * World!
  */;

MultilinePromotedPropertiesFixer

A constructor with promoted properties must have them in separate lines. Configuration options:

  • minimum_number_of_parameters (int): minimum number of parameters in the constructor to fix; defaults to 1
  • keep_blank_lines (bool): whether to keep blank lines between properties; defaults to false
 <?php class Foo {
-    public function __construct(private array $a, private bool $b, private int $i) {}
+    public function __construct(
+        private array $a,
+        private bool $b,
+        private int $i
+    ) {}
 }

NoCommentedOutCodeFixer

There can be no commented out code.

 <?php
-//var_dump($_POST);
 print_r($_POST);

NoDoctrineMigrationsGeneratedCommentFixer

There can be no comments generated by Doctrine Migrations.

 <?php
 namespace Migrations;
 use Doctrine\DBAL\Schema\Schema;
-/**
- * Auto-generated Migration: Please modify to your needs!
- */
 final class Version20180609123456 extends AbstractMigration
 {
     public function up(Schema $schema)
     {
-        // this up() migration is auto-generated, please modify it to your needs
         $this->addSql("UPDATE t1 SET col1 = col1 + 1");
     }
     public function down(Schema $schema)
     {
-        // this down() migration is auto-generated, please modify it to your needs
         $this->addSql("UPDATE t1 SET col1 = col1 - 1");
     }
 }

NoDuplicatedArrayKeyFixer

There can be no duplicate array keys. Configuration options:

  • ignore_expressions (bool): whether to keep duplicated expressions (as they might return different values) or not; defaults to true

     "bar" => 2,
     "foo" => 3,
 ];

 <?php
 namespace FooBar;
 use Foo;
-use Foo;
 use Bar;

NoImportFromGlobalNamespaceFixer

 <?php
 namespace Foo;
-use DateTime;
 class Bar {
-    public function __construct(DateTime $dateTime) {}
+    public function __construct(\DateTime $dateTime) {}
 }

NoLeadingSlashInGlobalNamespaceFixer

Classes in the global namespace cannot contain leading slashes.

 <?php
-$x = new \Foo();
+$x = new Foo();
 namespace Bar;
 $y = new \Baz();

NoNullableBooleanTypeFixer

There can be no nullable boolean types. Risky: when the null is used.

 <?php
-function foo(?bool $bar) : ?bool
+function foo(bool $bar) : bool
 {
      return $bar;
  }

NoPhpStormGeneratedCommentFixer

There can be no comments generated by PhpStorm.

 <?php

- * User: root
- * Date: 01.01.70
- * Time: 12:00
- */
 namespace Foo;

 <?php
 /**
- * Class Foo
  * Class to do something
  */
 class Foo {
     /**
-     * Get bar
      */
     function getBar() {}
 }

NoUselessDirnameCallFixer

Function dirname call must be removed if not needed.

 <?php
-require dirname(__DIR__) . "/vendor/autoload.php";
+require __DIR__ . "/../vendor/autoload.php";

NoUselessDoctrineRepositoryCommentFixer

There can be no comments generated by Doctrine ORM.

 <?php
-/**
- * FooRepository
- *
- * This class was generated by the Doctrine ORM. Add your own custom
- * repository methods below.
- */
 class FooRepository extends EntityRepository {}

NoUselessParenthesisFixer

There must be no useless parentheses.

 <?php
-foo(($bar));
+foo($bar);

NoUselessStrlenFixer

The strlen or mb_strlen functions should not be compared against 0. Risky: when the function strlen is overridden.

 <?php
-$isEmpty = strlen($string) === 0;
-$isNotEmpty = strlen($string) > 0;

+echo 135798642; // decimal
+echo 1234.45678e-4321; // float
+echo 0xAEB042FC; // hexadecimal
+echo 01234567; // octal

PhpUnitAssertArgumentsOrderFixer

PHPUnit assertions must have expected argument before actual one. Risky: when original PHPUnit methods are overwritten.

 <?php
 class FooTest extends TestCase {
     public function testFoo() {
-        self::assertSame($value, 10);
+        self::assertSame(10, $value);
     }
 }

PhpUnitDedicatedAssertFixer

PHPUnit assertions like assertCount and assertInstanceOf must be used over assertEquals/assertSame. Risky: when original PHPUnit methods are overwritten.

 <?php
 class FooTest extends TestCase {
     public function testFoo() {
-        self::assertSame($size, count($elements));
-        self::assertSame($className, get_class($object));
+        self::assertCount($size, $elements);
+        self::assertInstanceOf($className, $object);
     }
 }

PhpUnitNoUselessReturnFixer

PHPUnit fail, markTestIncomplete and markTestSkipped functions should not be followed directly by return. Risky: when original PHPUnit methods are overwritten.

 class FooTest extends TestCase {
     public function testFoo() {
         $this->markTestSkipped();
-        return;
     }
 }

PhpdocArrayStyleFixer

Generic array style should be used in PHPDoc.

 <?php
 /**

 $bar = new Foo();

PhpdocNoSuperfluousParamFixer

There must be no superfluous parameters in PHPDoc.

 <?php
 /**
  * @param bool $b
- * @param int $i
  * @param string $s this is string

  */
 function foo($b, $s) {}

PhpdocOnlyAllowedAnnotationsFixer

Only the listed annotations are allowed in PHPDoc. Configuration options:

  • elements (array): list of annotations to keep in PHPDoc; defaults to []

  * @version 1.0
  */
 function foo_bar() {}

PhpdocParamOrderFixer

The @param annotations must be in the same order as the function parameters. DEPRECATED: use phpdoc_param_order instead.

 <?php
 /**
  * @param string $foo
- * @param        $bar
+ * @param mixed  $bar
  */
 function a($foo, $bar) {}

PhpdocSelfAccessorFixer

In PHPDoc, the class or interface element self should be preferred over the class name itself.

 <?php
 class Foo {
     /**
-     * @var Foo
+     * @var self
      */
      private $instance;
 }

PhpdocSingleLineVarFixer

The @var annotations must be on a single line if they are the only content.

 <?php
 class Foo {

-     */
+    /** @var string */
     private $name;
 }
