Static interfaces are also available:, _(*5)

<?php

namespace ICanBoogie;

# Static inflector

echo StaticInflector::pluralize('genou', 'fr');      // "genoux"
echo StaticInflector::singularize('lærere', 'nb');   // "lærer"
echo StaticInflector::pluralize('üçgen', 'tr');      // "üçgenler"

# Helper functions
echo pluralize('child');                             // "children"
echo pluralize('genou', 'fr');                       // "genoux"
echo singularize('lærere', 'nb');                    // "lærer"
echo pluralize('üçgen', 'tr');                       // "üçgenler"

[!WARNING] Since v3.0 the file with the helper functions is no longer included in the autoload. You need to include the file vendor/icanboogie/inflector/lib/helpers.php in your composer.json if you want to continue using these functions., _(*6)

About inflections

Inflections are localized, the configurators are kept in lib/Inflections/., _(*7)

[!TIP] Since v2.1, these configurators are autoloaded classes, which means, in theory, you could add your own or overwrite those already defined by specifying another ICanBoogie\\Inflections\\ in your composer.json file., _(*8)

Acknowledgements

Most of the code and documentation was adapted from Ruby On Rails's Inflector and David Celis' inflections., _(*9)

Significant differences:, _(*10)

• Better support of accented characters.
• The Ruby module separator :: as been replaced by the PHP namespace separator \.
• The plural of "octopus" is "octopuses" (not "octopi"), the plural of "virus" is "viruses" (not viri), and the plural of "cow" is "cows" (not "kine").
• The following methods have been removed: tableize, classify, demodulize, constantize, deconstantize and foreign_key. They can be easily implemented in specific inflectors.
• Added the hyphenate method, which is a combination of underscore and dasherize.
• One specifies true rather than false to camelize() to downcase the first letter of the camel-cased string.

Getting started

Inflector expects to work in UTF-8, which is the default encoding character set starting PHP 5.6, if your configuration is different, use mb_internal_encoding() as follows:, _(*11)

<?php

namespace ICanBoogie;

// …

mb_internal_encoding('UTF-8');

titleize("été_aux_âmes_inouïes"); // Été Aux Âmes Inouïes
