How can the PHP manual be utilized effectively for guidance on updating MySQL data with CSV files?

To update MySQL data with CSV files using PHP, you can refer to the PHP manual for guidance on functions like `fgetcsv()` to read the CSV file and `mysqli_query()` to update the MySQL database with the extracted data. By combining these functions and handling errors properly, you can efficiently update your database with the information from the CSV file. 

<?php

$filename = "data.csv";
$handle = fopen($filename, "r");

if ($handle !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $query = "UPDATE your_table SET column1 = '{$data[0]}', column2 = '{$data[1]}' WHERE id = '{$data[2]}'";
        mysqli_query($connection, $query);
    }
    fclose($handle);
} else {
    echo "Error opening file.";
}

?>
