How can PHP developers optimize the output of query results in PHP to meet specific formatting requirements, such as exporting to CSV for further analysis?

To optimize the output of query results in PHP for specific formatting requirements, such as exporting to CSV for further analysis, developers can use PHP functions like fputcsv to format the data appropriately before writing it to a CSV file. By iterating through the query results and formatting each row as an array, developers can easily export the data in CSV format. 

// Assume $queryResults is an array of query results

$csvFileName = 'output.csv';
$csvFile = fopen($csvFileName, 'w');

// Write the header row to the CSV file
$header = array_keys($queryResults[0]);
fputcsv($csvFile, $header);

// Write each row of query results to the CSV file
foreach ($queryResults as $row) {
    fputcsv($csvFile, $row);
}

fclose($csvFile);
echo "CSV file generated successfully!";
