How can debugging techniques be effectively utilized to identify and fix errors in PHP scripts?

Issue: Debugging techniques can be effectively utilized to identify and fix errors in PHP scripts by using tools like var_dump() or print_r() to display the contents of variables and arrays, using error_reporting(E_ALL) to display all errors and warnings, and using step-by-step debugging with tools like Xdebug to trace the execution flow and identify the root cause of the issue.

<?php
// Enable error reporting to display all errors and warnings
error_reporting(E_ALL);

// Use var_dump() to display the contents of variables and arrays
$var = "Hello, World!";
var_dump($var);

// Use Xdebug for step-by-step debugging to trace the execution flow
// Install Xdebug extension and configure your IDE for debugging
