What steps can be taken to troubleshoot and debug PHP scripts that are not functioning as expected, such as always returning the same result?

The issue of a PHP script always returning the same result could be due to a variety of reasons, such as incorrect logic, syntax errors, or variable scope issues. To troubleshoot and debug this, you can start by checking for any syntax errors, ensuring that variables are properly initialized and used, and using debugging tools like var_dump() to inspect variable values at different points in the script. 

// Example PHP code snippet for troubleshooting and debugging a script that always returns the same result

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

// Ensure variables are properly initialized and used
$number = 10;
$result = $number * 2;

// Use var_dump() to inspect variable values
var_dump($result);
