How can debugging techniques help in identifying and resolving PHP form processing errors?

Debugging techniques can help in identifying and resolving PHP form processing errors by allowing developers to step through the code, check variable values, and pinpoint where the issue is occurring. By using tools like error reporting, var_dump(), and print_r(), developers can quickly identify the source of the error and make necessary corrections. 

<?php
// Enable error reporting to display any PHP errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Use var_dump() or print_r() to check the values of variables
var_dump($_POST);

// Check for any syntax errors or logical mistakes in the form processing code
// Fix any issues identified through debugging techniques
?>
