How can isolating individual steps in a PHP script help in troubleshooting complex issues?

Isolating individual steps in a PHP script can help in troubleshooting complex issues by allowing you to pinpoint where exactly the problem lies. By breaking down the script into smaller parts, you can test each step separately to identify any errors or unexpected behavior. This approach can help you narrow down the root cause of the issue and make it easier to fix. 

// Example PHP code snippet demonstrating how to isolate individual steps in a script

// Step 1: Retrieve data from database
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);

// Step 2: Process the retrieved data
if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process each row of data
    }
} else {
    echo "Error: Unable to retrieve data from database";
}

// Step 3: Display the processed data
// This step can be isolated for troubleshooting purposes
// echo $processedData;
