Features
--------

[](#features)

### Classes, interfaces and traits

[](#classes-interfaces-and-traits)

This sniff covers not only classes but also interfaces and traits.

### Namespaces and class names

[](#namespaces-and-class-names)

This sniff checks whether both of namespaces and class names match PSR-4 project structure.

### Configuration free

[](#configuration-free)

As this sniff respects `composer.json` [autoloading configuration](https://getcomposer.org/doc/04-schema.md#psr-4), you don't have to declare mapping between namespace prefixes and base directories.

### Psr4Fixer of PHP-CS-Fixer

[](#psr4fixer-of-php-cs-fixer)

[Psr4Fixer](https://github.com/FriendsOfPHP/PHP-CS-Fixer/blob/master/src/Fixer/Basic/Psr4Fixer.php) checkes if class names should match the file name and fixes the class names if its don't correspond to the file names. It doesn't check the namespaces.

In contrast, this package checks not only class names but also namespaces.

### SlevomatCodingStandard.Files.TypeNameMatchesFileName

[](#slevomatcodingstandardfilestypenamematchesfilename)

[SlevomatCodingStandard.Files.TypeNameMatchesFileName](https://github.com/slevomat/coding-standard#slevomatcodingstandardfilestypenamematchesfilename) is a custom PHP Code Sniffer sniff to check whether namespaces and class names follow PSR-0/PSR-4 project structure.

This sniff is similar to suin/phpcs-psr4-sniff, but it needs explicit configuration about the PSR-0/PSR-4 project structure. suin/phpcs-psr4-sniff takes implicit way as it follows the autoloding configuration of Composer.

[](#installation)

```
composer require --dev suin/phpcs-psr4-sniff

```

```
