TypeLang 解析器的参考实现。

TypeLang 是一种受静态分析器如 PHPStan 和 Psalm 启发的声明性类型语言。

阅读 文档页面 了解更多信息。

安装

TypeLang 解析器作为 Composer 仓库提供，可以在项目根目录下使用以下命令安装

composer require type-lang/parser

快速开始

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

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

var_dump($type);

预期输出
