How can debugging tools be used to identify errors in PHP code?

Debugging tools such as Xdebug can be used to identify errors in PHP code by providing detailed information about the execution flow, variable values, and stack traces. By setting breakpoints, stepping through code, and inspecting variables, developers can pinpoint the source of errors more efficiently.

// Example of using Xdebug to identify errors in PHP code
// Enable Xdebug in your PHP configuration

// Set a breakpoint in the code where you suspect an error
$x = 10;
$y = 0;

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

// Run the code with Xdebug enabled and inspect variable values to identify the error
