Installation

TypeLang Parser is available as Composer repository and can be installed using the following command in a root of your project:

composer require type-lang/parser

Quick Start

$parser = new \TypeLang\Parser\Parser();

$type = $parser->parse(<<<'PHP'
    array{
        key: callable(Example, int): mixed,
        ...
    }
    PHP);

var_dump($type);

Expected Output:
