Description

The main goal of this extension is to help PHPStan to detect the types after using Psl\Type\shape.

Given the following example:

use Psl\Type;

$specification = Type\shape([
    'name' => Type\string(),
    'age' => Type\int(),
    'location' => Type\optional(Type\shape([
        'city' => Type\string(),
        'state' => Type\string(),
        'country' => Type\string(),
    ]))
]);

$input = $specification->coerce($_GET['user']);

PHPStan assumes that $input is of type array<"age"|"location"|"name", array<"city"|"country"|"state", string>|int|string>.

If we enable the extension, you will get a more specific and correct type of array{name: string, age: int, location?: array{city: string, state: string, country: string}}.

Besides coerce, this extension also supports matches() and assert() methods.
