What are the advantages and disadvantages of using .csv files versus .inc.php files for updating variables?

When updating variables in PHP, using .csv files can be advantageous for easily storing and accessing data in a structured format. However, .csv files may not be secure for storing sensitive information and may require additional parsing to update variables. On the other hand, using .inc.php files can provide better security by keeping sensitive data within PHP code, but may be less flexible for updating variables without editing the code directly.

// Using .csv file to update variables
$csvFile = 'data.csv';
$handle = fopen($csvFile, 'r');
$data = fgetcsv($handle);
$variable1 = $data[0];
$variable2 = $data[1];
fclose($handle);

// Using .inc.php file to update variables
include 'data.inc.php';
$variable1 = $data['variable1'];
$variable2 = $data['variable2'];
