PHP Extension Feature Samples

This repository is a collection of sample features for a php extension. Each branch implements a single feature. Basically I add my tests as branches as I am learning and experimenting.

The minimum version is PHP 8 (originally PHP 7). I am not going to implement BC for older versions.

Compiling An Extension

Inside the extension directory:

1. Initialize with phpize
2. Configure with ./configure
3. Compile with make

Testing You Extension

PHP uses PHPT files for tests. The format is documented on the phpQA pages.

make test will compile your extension and run the tests.

Argument Information

PHP needs argument information for the functions and methods. Since PHP 8 you can define the stubs in PHP and generate the argument information from them.

Create a php file that ends with .stub.php. Define the your extension API as empty stubs. Call build/gen_stubs.php from the main php repository inside the extension directory to generate/update the argument information.

$ ../php-src/build/gen_stubs.php

If all goes well this will result in a C header file that ends with _arginfo.h for each stub file that you can include in the extension C file.
