What steps can be taken to troubleshoot when a PHP script, like the thermometer generator, does not display the expected output?

If a PHP script like the thermometer generator is not displaying the expected output, it could be due to syntax errors, variable mismanagement, or incorrect logic in the code. To troubleshoot, check for any error messages, review the code for typos or missing semicolons, and ensure that variables are properly defined and used. Additionally, verify that the logic of the script is correctly implemented to generate the desired output. 

<?php
// Check for syntax errors and typos
// Make sure variables are properly defined and used
// Verify that the logic of the script is correctly implemented

// Example: Correcting syntax errors and ensuring proper variable usage
$temperature = 25;

if ($temperature < 0) {
    echo "It's freezing cold!";
} elseif ($temperature >= 0 && $temperature <= 10) {
    echo "It's cold.";
} elseif ($temperature > 10 && $temperature <= 20) {
    echo "It's cool.";
} elseif ($temperature > 20 && $temperature <= 30) {
    echo "It's warm.";
} else {
    echo "It's hot!";
}
?>
