Does anyone know of a PHP library that handles matrix multiplication, inversion, etc.?

There is a relatively recent library for Linear Regression for PHP. This library does contain classes for matrix multiplication, and unit tests with 100% code coverage.
You could try the Math_Matrix library. I haven't used it, but it seems to be fairly comprehensive, going beyond simple matrix arithmetic to also include things like calculating the determinant or solving systems of equations.
