High-performance Linear Algebra & NLP extension for PHP (Zephir + OpenBLAS)

[rernesto]

I’ve been working on a production-grade PHP extension that brings core scientific-computing primitives into PHP, implemented in Zephir with C/OpenBLAS backends.

The intent is straightforward:
make PHP viable for numeric, ML, and IR workloads without leaving the PHP runtime.

Features

• Vector operations: dot product, norms (L1 / L2 / L∞), normalization
• Vector distances: Manhattan, Euclidean, Minkowski (Lp), Cosine
• Matrix SVD (values / reduced / full) via LAPACK / OpenBLAS
• NLP support: Snowball stemming (libstemmer)
• Clean PHP API with explicit constants (no magic numbers)

The extension is fully usable as-is, but it may also be useful as a reference for advanced Zephir patterns (optimizers, ABI design, OpenBLAS integration).
