Are there specific PHP functions or methods that can help streamline the process of exporting CSV files without including HTML content?

When exporting CSV files in PHP, it's important to ensure that only the data is included in the file without any HTML content. To streamline this process, you can use the `fputcsv()` function in PHP, which formats an array as a CSV line and writes it to a file pointer. By using this function, you can easily export data to a CSV file without worrying about including any HTML content.

// Sample data to be exported to CSV
$data = array(
    array('John Doe', 'john.doe@example.com', 'New York'),
    array('Jane Smith', 'jane.smith@example.com', 'Los Angeles'),
    array('Mike Johnson', 'mike.johnson@example.com', 'Chicago')
);

// Open a file pointer for writing
$fp = fopen('export.csv', 'w');

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

// Close the file pointer
fclose($fp);
