What are some best practices when migrating JavaScript modules to PHP?

When migrating JavaScript modules to PHP, it's important to understand the differences in syntax and functionality between the two languages. One best practice is to use PHP's built-in functions and classes to replicate the behavior of the JavaScript modules. Additionally, make sure to properly handle data types and conversions to ensure compatibility between the two languages.

// Example code snippet to migrate a JavaScript module that calculates the sum of an array to PHP

function calculateSum($array) {
    $sum = array_sum($array);
    return $sum;
}

// Usage
$array = [1, 2, 3, 4, 5];
$sum = calculateSum($array);
echo $sum; // Output: 15
