What are the benefits of using CSV format for exporting data to Excel from PHP applications?

When exporting data to Excel from PHP applications, using the CSV format is beneficial because it is a simple and widely supported format that Excel can easily import. CSV files can store tabular data with a comma-separated format, making it easy to read and manipulate in Excel. Additionally, exporting data to CSV is efficient and does not require any special libraries or plugins.

// Sample PHP code to export data to CSV format for Excel

// Sample data to export
$data = array(
    array('Name', 'Age', 'Email'),
    array('John Doe', 25, 'john.doe@example.com'),
    array('Jane Smith', 30, 'jane.smith@example.com')
);

// Set headers to force download
header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="export.csv"');

// Open output stream
$fp = fopen('php://output', 'w');

// Loop through data and write to CSV
foreach ($data as $row) {
    fputcsv($fp, $row);
}

// Close the output stream
fclose($fp);
