Where can I download a debugger for PHP?

To debug PHP code effectively, you can use a debugger like Xdebug. Xdebug is a popular PHP extension that provides debugging and profiling capabilities for PHP applications. You can download Xdebug from the official website or install it using package managers like PECL.

// Sample PHP code with Xdebug debugging enabled
$x = 10;
$y = 20;
$sum = $x + $y;

// Start debugging session
xdebug_start_trace();

// Output the sum
echo $sum;

// Stop debugging session
xdebug_stop_trace();
