Major new features 🚀

Support for custom type aliases (phpstan/phpstan-src@3151160)

Type aliases (also known as typedef) are a popular feature in other languages like TypeScript or C++. Using the following configuration in phpstan.neon will allow you to reference these types in your PHPDocs:

parameters:
    typeAliases:
        Name: 'string'
        NameResolver: 'callable(): string'
        NameOrResolver: 'Name|NameResolver'

/**
 * @param NameOrResolver $arg
 */
function foo($arg)
{
    // $arg is string|(callable(): string)
}

The development of this feature was sponsored by @tslettebo.
