php-opencv

Why we included this project

PHP developers who want OpenCV features without spinning up a separate Python or C++ service can use this extension to call the library directly from PHP. It wraps OpenCV's image operations, CascadeClassifier face detection, and LBPH face recognition in PHP classes and functions, so the same codebase that serves your web app can also read and process images. The project is no longer maintained, and that caveat matters: treat it as a reference implementation and a starting point, not a dependency you can count on long term. The documented examples and a bundled Docker image with OpenCV and contrib modules make it fairly painless to get a working environment and see whether the API covers what you need. For teams already on PHP who want basic computer vision without adding another runtime, it's worth a look.
