Are there specific debugging techniques or tools recommended for troubleshooting PHP code, especially in the context of form processing?

When troubleshooting PHP code, especially in the context of form processing, it is recommended to use tools like Xdebug for step-by-step debugging, print statements for checking variable values, and error reporting functions like error_reporting() and ini_set() to display errors. 

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

// Use print statements to check variable values
echo "Form data: ";
print_r($_POST);

// Implement Xdebug for step-by-step debugging
// Example: Add breakpoints in your code and step through it with Xdebug-enabled IDE
