    PHP 8 string functions on PHP 7.2+, WordPress hook stubs, and translation/escaping passthroughs so toolkit code runs without booting WordPress.

Why this exists
---------------

[](#why-this-exists)

A lot of WordPress-adjacent code wants to call `esc_html()`, `__()`, or `apply_filters()` without booting WordPress. The polyfill component provides minimal implementations for the subset used by the toolkit, and stays out of the way when WordPress is loaded (every function uses `function_exists()` guards).

PHP 8 string functions on PHP 7.2
---------------------------------

[](#php-8-string-functions-on-php-72)

The polyfills define `str_contains`, `str_starts_with`, `str_ends_with`, and `array_key_first` only when missing.
