create

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Create a new Locale object

namespace HH\Lib\Locale;

function create(
  string $locale,
): Locale;

The input should be of the form country[.encoding], for example: "C", en_US, en_US.UTF-8.

If present, the encoding currently must be 'UTF-8'.

This will throw on 'magic' locales such as:

• the empty string: use from_environment()
• '0': use get_native()

Parameters

• string $locale

Returns

• Locale
