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.

您可以尝试 Math_Matrix 库。 我没有使用过它，但它似乎相当全面，超越了简单的矩阵算术，还包括计算行列式或求解方程组等内容。
