Introduction ============ The Doctrine Inflector has methods for inflecting text. The features include pluralization, singularization, converting between camelCase and under_score and capitalizing words. Installation ============ You can install the Inflector with composer: .. code-block:: console $ composer require doctrine/inflector Usage ===== Using the inflector is easy, you can create a new ``Doctrine\Inflector\Inflector`` instance by using the ``Doctrine\Inflector\InflectorFactory`` class: .. code-block:: php use Doctrine\Inflector\InflectorFactory; $inflector = InflectorFactory::create()->build(); By default it will create an English inflector. If you want to use another language, just pass the language you want to create an inflector for to the ``createForLanguage()`` method: .. code-block:: php use Doctrine\Inflector\InflectorFactory; use Doctrine\Inflector\Language; $inflector = InflectorFactory::createForLanguage(Language::SPANISH)->build(); The supported languages are as follows: - ``Language::ENGLISH`` - ``Language::FRENCH`` - ``Language::NORWEGIAN_BOKMAL`` - ``Language::PORTUGUESE`` - ``Language::SPANISH`` - ``Language::TURKISH`` If you want to manually construct the inflector instead of using a factory, you can do so like this: .. code-block:: php use Doctrine\Inflector\CachedWordInflector; use Doctrine\Inflector\RulesetInflector; use Doctrine\Inflector\Rules\English; $inflector = new Inflector( new CachedWordInflector(new RulesetInflector( English\Rules::getSingularRuleset() )), new CachedWordInflector(new RulesetInflector( English\Rules::getPluralRuleset() )) ); Adding Languages ---------------- If you are interested in adding support for your language, take a look at the other languages defined in the ``Doctrine\Inflector\Rules`` namespace and the tests located in ``Doctrine\Tests\Inflector\Rules``. You can copy one of the languages and update the rules for your language. Once you have done this, send a pull request to the ``doctrine/inflector`` repository with the additions. Custom Setup ============ If you want to setup custom singular and plural rules, you can configure these in the factory: .. code-block:: php use Doctrine\Inflector\InflectorFactory; use Doctrine\Inflector\Rules\Pattern; use Doctrine\Inflector\Rules\Patterns; use Doctrine\Inflector\Rules\Ruleset; use Doctrine\Inflector\Rules\Substitution; use Doctrine\Inflector\Rules\Substitutions; use Doctrine\Inflector\Rules\Transformation; use Doctrine\Inflector\Rules\Transformations; use Doctrine\Inflector\Rules\Word; $inflector = InflectorFactory::create() ->withSingularRules( new Ruleset( new Transformations( new Transformation(new Pattern('/^(bil)er$/i'), '\1'), new Transformation(new Pattern('/^(inflec|contribu)tors$/i'), '\1ta') ), new Patterns(new Pattern('singulars')), new Substitutions(new Substitution(new Word('spins'), new Word('spinor'))) ) ) ->withPluralRules( new Ruleset( new Transformations( new Transformation(new Pattern('^(bil)er$'), '\1'), new Transformation(new Pattern('^(inflec|contribu)tors$'), '\1ta') ), new Patterns(new Pattern('noflect'), new Pattern('abtuse')), new Substitutions( new Substitution(new Word('amaze'), new Word('amazable')), new Substitution(new Word('phone'), new Word('phonezes')) ) ) ) ->build(); No operation inflector ---------------------- The ``Doctrine\Inflector\NoopWordInflector`` may be used to configure an inflector that doesn't perform any operation for pluralization and/or singularization. If will simply return the input as output. This is an implementation of the `Null Object design pattern <https://sourcemaking.com/design_patterns/null_object>`_. .. code-block:: php use Doctrine\Inflector\Inflector; use Doctrine\Inflector\NoopWordInflector; $inflector = new Inflector(new NoopWordInflector(), new NoopWordInflector()); Tableize ======== Converts ``ModelName`` to ``model_name``: .. code-block:: php echo $inflector->tableize('ModelName'); // model_name Classify ======== Converts ``model_name`` to ``ModelName``: .. code-block:: php echo $inflector->classify('model_name'); // ModelName Camelize ======== This method uses `Classify`_ and then converts the first character to lowercase: .. code-block:: php echo $inflector->camelize('model_name'); // modelName Capitalize ========== Takes a string and capitalizes all of the words, like PHP's built-in ``ucwords`` function. This extends that behavior, however, by allowing the word delimiters to be configured, rather than only separating on whitespace. Here is an example: .. code-block:: php $string = 'top-o-the-morning to all_of_you!'; echo $inflector->capitalize($string); // Top-O-The-Morning To All_of_you! echo $inflector->capitalize($string, '-_ '); // Top-O-The-Morning To All_Of_You! Pluralize ========= Returns a word in plural form. .. code-block:: php echo $inflector->pluralize('browser'); // browsers Singularize =========== Returns a word in singular form. .. code-block:: php echo $inflector->singularize('browsers'); // browser Urlize ====== Generate a URL friendly string from a string of text: .. code-block:: php echo $inflector->urlize('My first blog post'); // my-first-blog-post Unaccent ======== You can unaccent a string of text using the ``unaccent()`` method: .. code-block:: php echo $inflector->unaccent('año'); // ano Legacy API ========== The API present in Inflector 1.x is still available, but will be deprecated in a future release and dropped for 3.0. Support for languages other than English is available in the 2.0 API only. Acknowledgements ================ The language rules in this library have been adapted from several different sources, including but not limited to: - `Ruby On Rails Inflector <http://api.rubyonrails.org/classes/ActiveSupport/Inflector.html>`_ - `ICanBoogie Inflector <https://github.com/ICanBoogie/Inflector>`_ - `CakePHP Inflector <https://book.cakephp.org/3.0/en/core-libraries/inflector.html>`_
