What are some best practices for determining a mathematical function from extreme values in PHP?

When determining a mathematical function from extreme values in PHP, it is essential to use regression analysis to find the best-fit curve that represents the data accurately. This can be achieved by using mathematical libraries or functions that support regression analysis in PHP, such as the `PHP-ML` library. By fitting a curve to the extreme values, you can then use the resulting function to make predictions or analyze the data further. 

// Example code using PHP-ML library for regression analysis
use Phpml\Regression\LeastSquares;

// Sample extreme values data
$data = [
    [1, 10],
    [2, 20],
    [3, 30],
    [4, 40],
    [5, 50],
];

// Initialize the Least Squares regression algorithm
$regression = new LeastSquares();
$regression->train($data);

// Get the coefficients of the best-fit curve
$coefficients = $regression->getCoefficients();

// Use the coefficients to create a mathematical function
function calculateFunction($x) {
    global $coefficients;
    return $coefficients[0] + $coefficients[1] * $x;
}

// Example usage
echo calculateFunction(6); // Output: 60
