This is available as Str\ends_with_ci_l in the www repository.

Returns whether the string ends with the given suffix (case-insensitive)

namespace HH\Lib\Str;

function ends_with_ci_l(
  \HH\Lib\Locale\Locale $locale,
  string $string,
  string $suffix,
): bool;

Locale-specific rules for case-insensitive comparisons will be used, and strings will be normalized before comparing if the locale specifies an encoding that supports multiple representations of the same characters, such as UTF-8.

For a case-sensitive check, see Str\ends_with_l().
