Description
Applications running on PHP 8.4 can format, compare, normalize, and translate locale-sensitive data. This runtime extension adds ICU-backed APIs for dates, numbers, calendars, collation, message formatting, and Unicode normalization. It is dependency-only and has no separate launcher; PHP code calls Intl classes when enabled. Locale choices affect user-visible text and sorting, so apps should test important languages and avoid mixing formats in stored data.
