How can you debug a PHP script in NetBeans to see the execution line by line?

To debug a PHP script in NetBeans to see the execution line by line, you can set breakpoints in your code by clicking on the left margin of the line number where you want to pause execution. Then, you can start the debugger by clicking on the debug icon or pressing Ctrl+F5. This will allow you to step through your code line by line, inspect variables, and see the flow of execution.

<?php

// Sample PHP script with debugging in NetBeans
$x = 5;
$y = 10;
$z = $x + $y;

// Set breakpoints on the following lines
// Click on the left margin of the line number

$result = $z * 2;

echo $result;

?>
