How can PHP be used to calculate dimensional weight for shipping packages?

To calculate dimensional weight for shipping packages, you need to determine the volumetric weight of the package based on its dimensions. This is often used by shipping companies to ensure that they are charging appropriately for larger, lightweight packages. To calculate dimensional weight, you typically need to know the length, width, and height of the package, as well as the dimensional weight factor used by the shipping company.

function calculateDimensionalWeight($length, $width, $height, $dimensionalWeightFactor) {
    $volumetricWeight = ($length * $width * $height) / $dimensionalWeightFactor;
    return $volumetricWeight;
}

$length = 10; // in inches
$width = 8; // in inches
$height = 6; // in inches
$dimensionalWeightFactor = 166; // factor used by shipping company

$dimensionalWeight = calculateDimensionalWeight($length, $width, $height, $dimensionalWeightFactor);
echo "The dimensional weight of the package is: " . $dimensionalWeight;
