Does PHP have built-in support for matrix operations, or should one define their own algorithms or use external libraries?

PHP does not have built-in support for matrix operations. To perform matrix operations in PHP, one can either define their own algorithms or use external libraries such as MathPHP or PHPMatrix. These libraries provide functions for matrix addition, subtraction, multiplication, transposition, inversion, and other common operations. 

// Example using MathPHP library for matrix operations
require_once 'vendor/autoload.php'; // Include MathPHP library

use MathPHP\LinearAlgebra\Matrix;

// Create two matrices
$matrix1 = Matrix::create([[1, 2], [3, 4]]);
$matrix2 = Matrix::create([[5, 6], [7, 8]]);

// Perform matrix addition
$result = $matrix1->add($matrix2);

// Display the result
echo $result->toString();
