Are PHP array keys ever translated?

No. Keys are never read for translation and never modified. Note: the output is always clean, reformatted PHP with single-quoted strings — original whitespace style and inline comments are not preserved in the output.

What happens to Laravel :placeholder variables?

We instruct the AI to leave :name, :count, and similar placeholder patterns untouched. Only the surrounding human-readable text is translated. The output is safe to pass directly to Laravel's __() helper.

What about numbers, booleans, and null values?

They pass through completely untouched. Only string values are extracted for translation. 'active' => true, 'count' => 42, 'data' => null — all preserved exactly.

Is deeply nested PHP supported?

Yes. The handler uses a recursive descent parser that handles arbitrarily nested arrays. Nesting is fully preserved — your deeply nested translation groups come back identical in structure.
