What are the best practices for reading and processing CSV files in PHP to avoid encoding issues?

When reading and processing CSV files in PHP, it's important to handle encoding properly to avoid issues with special characters. One way to do this is by using the `fgetcsv()` function with the `mb_convert_encoding()` function to convert the data to the desired encoding. 

// Open the CSV file
$handle = fopen('file.csv', 'r');

// Loop through each row in the CSV file
while (($data = fgetcsv($handle)) !== false) {
    // Convert each field to UTF-8 encoding
    foreach ($data as $key => $value) {
        $data[$key] = mb_convert_encoding($value, 'UTF-8', 'auto');
    }
    // Process the data as needed
    // ...
}

// Close the CSV file
fclose($handle);
