What are the best practices for debugging PHP scripts to identify and resolve issues with form data processing?

Issue: When processing form data in PHP scripts, it can be challenging to identify and resolve issues that may arise, such as incorrect data being submitted or errors in the processing logic. To debug these issues effectively, it is important to use proper error handling techniques, validate input data, and utilize debugging tools like var_dump() or print_r() to inspect variables and data structures. 

// Example PHP script for processing form data with debugging practices

// Validate input data
if(isset($_POST['submit'])) {
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Debugging with var_dump()
    var_dump($name, $email);
    
    // Processing logic
    // Add further processing code here
}
