What are the recommended steps for debugging PHP scripts that are not displaying expected results in the browser?

When debugging PHP scripts that are not displaying expected results in the browser, it's important to check for syntax errors, ensure variables are correctly initialized and used, and verify that functions are returning the expected values. One common approach is to use print statements or var_dump() to output variables and values at different points in the script to identify where the issue may lie. 

<?php
// Example PHP script with debugging statements

// Check for syntax errors
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Initialize variables
$number1 = 10;
$number2 = 20;

// Perform calculation
$result = $number1 * $number2;

// Output debugging information
var_dump($result);

// Display result
echo "The result of the calculation is: " . $result;
?>
