Features:

• 🔁 automatic case detection
• 🏭 factory
• 🌐 i18n

Usage

The input string's format is detected automatically.

For example:

use Jawira\CaseConverter\Convert;

$hero = new Convert('john-connor');

echo $hero->toCamel();   // output: johnConnor

You can also specify the input string's format explicitly:

echo $hero->fromKebab()->toSnake();   // output: john_connor

You can also use the provided factory to create a Convert instance. See the list of all public methods for more options.

i18n

The library supports non-English alphabets:

// Spanish
$esp = new Convert('DON_RAMÓN_Y_ÑOÑO');
echo $esp->toCamel();   // output: donRamónYÑoño

// Greek
$grc = new Convert('πολύ-Καλό');
echo $grc->toCamel();   // output: πολύΚαλό

// Russian
$rus = new Convert('ОЧЕНЬ_ПРИЯТНО');
echo $rus->toCamel();   // output: оченьПриятно

case-converter supports both Simple Case-Mapping and Full Case-Mapping. Learn more about Case-Mapping.
