How can debugging techniques be applied to identify and fix errors in PHP code, especially when dealing with form data?

To identify and fix errors in PHP code, especially when dealing with form data, debugging techniques like using var_dump() or print_r() can be helpful in displaying the values of variables and arrays. Additionally, using error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) can help in identifying syntax errors or runtime errors in the code. By carefully examining the output of these debugging techniques, developers can pinpoint the issues and make necessary corrections. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Debugging form data
var_dump($_POST); // Display the values of POST data

// Fixing form data processing
if(isset($_POST['submit'])){
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Perform further processing or validation here
}
?>
