How can debugging tools like a PHP debugger be utilized to troubleshoot issues in the code?

Issue: When encountering bugs or issues in PHP code, a PHP debugger can be utilized to step through the code line by line, inspect variables, and identify the root cause of the problem. By setting breakpoints at specific points in the code, developers can analyze the program's behavior and track down errors more efficiently.

// Example PHP code snippet utilizing a PHP debugger to troubleshoot issues
// Set breakpoints at specific points in the code to analyze variables and program behavior

// Initialize PHP debugger
xdebug_break();

// Code logic here
$variable = 10;
$result = $variable * 2;

// More code logic
echo $result;
