azjezz/psl
PSL is a modern, well-typed standard library for PHP 8.4+, inspired by HHVM’s HSL. It offers safer, predictable APIs for async, collections, networking, I/O, crypto, terminal UI, and robust data validation—replacing brittle built-ins with consistent alternatives.
The Locale component provides a backed enum containing 700+ locale identifiers (such as en_US, fr_FR, ja_JP). Using an enum instead of raw strings eliminates typos, enables IDE autocompletion, and makes locale parameters type-safe throughout your application.
Pick a locale by name -- every case maps to its standard locale string:
@example('system/locale-select.php')
Locale::default() reads the locale configured via PHP's intl.default_locale setting. If no locale is configured or the configured value is not recognized, it falls back to Locale::English:
@example('system/locale-default.php')
Each locale instance exposes methods to extract its parts:
@example('system/locale-inspect.php')
Script-based locales also work:
@example('system/locale-script.php')
The Locale enum is used by PSL's DateTime formatting to produce locale-aware output:
@example('system/locale-datetime.php')
See src/Psl/Locale/ for the full API.
