How can developers effectively handle special characters, such as commas, when working with CSV files in PHP?

Special characters, such as commas, can cause issues when working with CSV files in PHP as they are used as delimiters. To handle special characters effectively, developers can enclose fields containing special characters within double quotes. This way, the CSV parser will treat the entire field as a single value. Additionally, developers can use functions like `fputcsv()` to automatically handle special characters when writing to CSV files. 

// Example code snippet to handle special characters in CSV files
$data = array(
    array('John Doe', 'john.doe@example.com', 'New York, USA'),
    array('Jane Smith', 'jane.smith@example.com', 'Los Angeles, USA'),
);

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

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

fclose($fp);
