Is it necessary to use a debugger when working with PHP, and if so, how can it be integrated into the development environment?

It is highly recommended to use a debugger when working with PHP to help identify and fix issues in the code. One popular debugger for PHP is Xdebug, which can be integrated into development environments like PhpStorm, Visual Studio Code, or Eclipse. By setting up Xdebug in your IDE, you can set breakpoints, step through code, inspect variables, and track the flow of your PHP application for easier debugging.

// Sample PHP code with a breakpoint set for debugging
$x = 10;
$y = 5;
$sum = $x + $y;
// Breakpoint set here
$result = $sum * 2;
echo $result;
