How can one troubleshoot and debug PHP code that is not generating the expected output or file?

To troubleshoot and debug PHP code that is not generating the expected output or file, you can start by checking for syntax errors, ensuring all variables are properly initialized, and using functions like echo or var_dump to display the values of variables at various points in your code. You can also use error reporting functions like error_reporting(E_ALL) and ini_set('display_errors', 1) to help identify any errors. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check for syntax errors
// Ensure all variables are properly initialized
// Use echo or var_dump to display variable values

// Example code snippet
$number = 5;
echo "The number is: " . $number;
?>
