What are some debugging steps to take when the retrieved shipping cost does not match the expected value in PHP?

When the retrieved shipping cost does not match the expected value in PHP, one possible issue could be incorrect calculation or retrieval of the shipping cost data. To debug this, you can start by checking the logic used to calculate the shipping cost, ensuring that the correct variables and formulas are being used. Additionally, verify that the shipping cost data is being retrieved accurately from the database or external API. 

// Check the logic used to calculate the shipping cost
// Make sure the correct variables and formulas are being used
// Verify that the shipping cost data is being retrieved accurately

// Example code snippet for debugging the shipping cost calculation
$baseShippingCost = 5.00;
$itemWeight = 2.5;
$shippingCost = $baseShippingCost + ($itemWeight * 2.00); // Example calculation logic

// Debugging output
echo "Base Shipping Cost: $baseShippingCost <br>";
echo "Item Weight: $itemWeight <br>";
echo "Calculated Shipping Cost: $shippingCost <br>";

// Check the retrieved shipping cost against the expected value
// Make adjustments to the calculation or retrieval logic as needed
