How can debugging tools help identify and resolve PHP code errors?

Debugging tools can help identify and resolve PHP code errors by providing insights into the execution flow, variable values, and potential issues within the code. By using tools like Xdebug, PHP Debug Bar, or PHPStorm's debugging features, developers can step through their code line by line, set breakpoints, and inspect variables to pinpoint the root cause of errors. These tools can also provide detailed error messages and stack traces to help developers quickly identify and fix issues in their PHP code.

// Example PHP code snippet using Xdebug to debug and fix code errors
// Enable Xdebug in your PHP configuration for debugging support

// Set a breakpoint to stop execution at a specific line
$x = 10;
$y = 0;

// Divide by zero error
$z = $x / $y;

echo $z;
