When working with CSV files in PHP, what are some strategies for handling data manipulation to avoid gaps or inconsistencies in the output?

When working with CSV files in PHP, one strategy to avoid gaps or inconsistencies in the output is to properly handle empty fields or missing values. You can achieve this by checking for empty values and replacing them with a default value or handling them in a way that ensures consistency in the output. 

// Read CSV file
$csv = array_map('str_getcsv', file('data.csv'));

// Loop through each row
foreach($csv as $row){
    // Check for empty fields and replace with default value
    foreach($row as $key => $value){
        if(empty($value)){
            $csv[$key] = 'N/A';
        }
    }
    
    // Process the data or output it in a consistent manner
    // e.g. echo or write to a new CSV file
}
