Question 1

How to install MathPHP with Composer?

Accepted Answer

Add 'markrogoyski/math-php:2.*' to your composer.json require section, then run 'composer install'. The library requires PHP 7.2 or higher, with version 1.* for PHP 7.0-7.1.

Question 2

MathPHP vs PHP's built-in math functions – which is better?

Accepted Answer

MathPHP offers far more functionality, like matrix operations and statistical distributions, beyond PHP's basic math functions. Use it for advanced computations; stick to built-ins for simple arithmetic to avoid overhead.

Question 3

How to perform matrix multiplication in MathPHP?

Accepted Answer

Use the Matrix class: create matrices with MatrixFactory::create(), then call $A->multiply($B). The README shows examples with LU decompositions and linear system solving for more complex operations.

Question 4

Can MathPHP handle big integers or arbitrary precision?

Accepted Answer

Yes, it includes an ArbitraryInteger class for arbitrary-length integers, supporting operations like addition, multiplication, and modulus. However, performance may degrade with extremely large numbers.

Question 5

Is MathPHP suitable for statistical analysis in web applications?

Accepted Answer

Absolutely – it provides descriptive statistics, regressions, ANOVA, and probability distributions. Built-in datasets like USArrests facilitate quick prototyping, though for heavy loads, consider caching results.

Question 6

What PHP version is required for MathPHP?

Accepted Answer

Version 2.* requires PHP 7.2 or later. For PHP 7.0 or 7.1, use version 1.*, as noted in the README's minimum requirements section.
