How can PHP beginners troubleshoot and debug issues in their form processing scripts effectively?

Issue: PHP beginners can troubleshoot and debug issues in their form processing scripts effectively by using error reporting, checking for syntax errors, using var_dump() or print_r() to inspect variables, and utilizing tools like Xdebug for more advanced debugging. 

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

// Check for syntax errors
if (syntax_error()) {
    echo "Syntax error found!";
}

// Inspect variables with var_dump() or print_r()
$variable = "example";
var_dump($variable);

// Utilize Xdebug for advanced debugging
xdebug_start_trace();
// Your code here
xdebug_stop_trace();
?>
