ext-duckdb

An exercise in using LLMs to generate a PHP extension - and to try to fill a gap in available PHP extensions.

I have the duckdb source code in duckdb/ and the PHP source code in php-src/ for easy reference.

Based on https://github.com/bogkonstantin/php-extension-hello-world. Original README below.
