What are common issues with CSV encoding in PHP scripts?

Common issues with CSV encoding in PHP scripts include handling special characters, ensuring proper delimiter usage, and maintaining consistent encoding throughout the file. To solve these issues, it is recommended to use PHP's built-in functions like `fputcsv()` to properly encode CSV data.

// Sample code snippet demonstrating proper CSV encoding using fputcsv()

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

$fp = fopen('data.csv', 'w');

foreach ($data as $fields) {
    fputcsv($fp, $fields);
}

fclose($fp);
