GlotPress exports the revision date of a `.l10n.php` file as `translation-revision-date`. That is what the language packs on WordPress.org ship, and what `make-json` in this package already emits for the same value. `make-php` wrote only `po-revision-date`, so its output diverged from the reference format. WordPress reads `po-revision-date` in `wp_get_l10n_php_file_data()`, so swapping the key outright would leave the revision date empty in `wp_get_installed_translations()` on every released version, and an up-to-date language pack would be offered again on each update check. Write both keys instead: existing readers keep working, and the file matches what GlotPress produces.

GlotPress writes `translation-revision-date` as the only revision date key in a `.l10n.php` file; `po-revision-date` appears nowhere in its exporter. Every language pack on WordPress.org therefore carries just the one key, so emitting both from `make-php` still diverged from the reference format. Drop `po-revision-date` and write only the GlotPress key. Note that `wp_get_l10n_php_file_data()` reads `po-revision-date`, so the revision date it reports for a file generated by `make-php` is empty until core reads the GlotPress key as well. That is already the case for every GlotPress-generated language pack.

💡 Result:
In WordPress core, the components you referenced relate to the translation system's infrastructure for handling PHP-based translation files (.l10n.php) and the centralized management of translation data [1][2][3]..l10n.php and Metadata The .l10n.php file format was introduced to provide a more performant alternative to traditional .mo and .po translation files [3]. WordPress uses the function wp_get_l10n_php_file_data() to extract specific header metadata from these files [1][4]. The headers extracted include [1]: - POT-Creation-Date (mapped from 'pot-creation-date') - PO-Revision-Date (mapped from 'po-revision-date') - Project-Id-Version (mapped from 'project-id-version') - X-Generator (mapped from 'x-generator') These headers are standard in Gettext PO/POT files, and wp_get_l10n_php_file_data ensures that PHP translation files maintain compatibility with this metadata structure [1][2]. WP_Translation_Controller Introduced in WordPress 6.5, WP_Translation_Controller serves as a core class for managing translation loading and retrieval [5][6]. It acts as a centralized controller to handle multiple translation files for a given text domain [5][7]. Key responsibilities of this controller include [5]: - Loading translation files (load_file) [6]. - Locating translations for strings within specific text domains and locales (locate_translation) [7]. - Managing the state of loaded files and translations [5][6]. - Providing utility methods to retrieve information about loaded files, such as headers, via get_headers() [5]. Together, these systems represent a modernization of WordPress's internationalization (i18n) stack, shifting toward more efficient PHP-based file parsing and centralized object-oriented management [3][5].

Preserve po-revision-date for WordPress compatibility.
wp_get_l10n_php_file_data() reads PO-Revision-Date from po-revision-date. PhpArrayGenerator::toArray() emits only translation-revision-date, so WordPress readers can lose the revision date. Emit both keys, or update the reader and end-to-end coverage in the same change. Update the features/makephp.feature scenario that currently asserts the legacy key is absent.

PhpArrayGenerator::toArray() and its headers_allowlist to emit the legacy

The problem
make-phpwrites the revision date of a generated.l10n.phpfile aspo-revision-date(src/PhpArrayGenerator.php).GlotPress — the reference producer of these files, and the one behind every language pack on WordPress.org — writes
translation-revision-date, and writes nopo-revision-dateat all:JedGeneratorin this package already usestranslation-revision-datefor the same value in the JSON output (src/JedGenerator.php), somake-phpwas the odd one out for a class whose docblock says it "returns output in the form WordPress uses".The change
make-phpnow emitstranslation-revision-dateinstead ofpo-revision-date, matching GlotPress exactly.What this means for
wp_get_l10n_php_file_data()Worth being explicit about, since this renames a key that something reads.
WordPress reads
po-revision-dateinwp_get_l10n_php_file_data(), added in 6.6 and unchanged since, and that value feedswp_get_installed_translations(). After this change, the revision date core reports for amake-php-generated file is empty on currently released WordPress versions.That is already the situation for every language pack shipped from WordPress.org, because GlotPress never writes
po-revision-date—wp_get_l10n_php_file_data()returns an empty revision date for those files today. So this alignsmake-phpoutput with the files core already receives in practice, rather than opening a new gap.Core is separately looking at reading
translation-revision-datein that function (Trac #65809).The alternative would be to write both keys, which keeps the value readable on current WordPress versions at the cost of no longer matching the reference format byte for byte. This PR deliberately takes the matching-GlotPress route.
Testing
features/makephp.featuregains a scenario asserting that a PO withPO-Revision-Dateproducestranslation-revision-dateand nopo-revision-date. The existing "Does include headers" scenario, which asserts the full generated array, is updated for the renamed key.Summary by CodeRabbit
