How can debugging tools like xDebug be used to troubleshoot PHP code?

xDebug can be used to troubleshoot PHP code by allowing developers to step through their code line by line, set breakpoints, inspect variables, and track function calls. This can help identify errors, logic issues, or unexpected behavior in the code. 

<?php
// Enable xDebug in your PHP configuration

// Set breakpoints in your code where you suspect issues
// For example:
function calculateSum($a, $b) {
    $sum = $a + $b; // Set a breakpoint here
    return $sum;
}

// Use xDebug-enabled IDE to step through the code and inspect variables
// This can help identify and fix any issues in the code
?>
