What debugging steps can be taken to identify and resolve issues with data transfer in PHP scripts?

Issue: If data transfer in PHP scripts is not working properly, it could be due to errors in the code handling the data transfer. To identify and resolve these issues, you can start by checking for any syntax errors, ensuring that the correct variables are being used, and verifying that the data is being sent and received correctly. 

// Example PHP code snippet to debug data transfer issues

// Check for any syntax errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Ensure correct variables are being used
$data = $_POST['data']; // Assuming data is being sent via POST method

// Verify data is being sent and received correctly
if(isset($data)) {
    // Data transfer successful
    // Your code here to process the data
} else {
    // Data transfer failed
    echo "Error: Data transfer failed";
}
