How can PHP errors and warnings be effectively debugged and resolved in form processing scripts?

To effectively debug and resolve PHP errors and warnings in form processing scripts, it is important to enable error reporting, check for syntax errors, and use functions like error_reporting() and ini_set() to display errors. Additionally, using tools like Xdebug can help in pinpointing the exact cause of the error. 

// Enable error reporting
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Your form processing code goes here
// Make sure to sanitize and validate input data
