What are some best practices for efficiently updating multiple data entries in a table using PHP?

When updating multiple data entries in a table using PHP, it is best practice to use prepared statements to prevent SQL injection attacks and improve performance. Additionally, you can use a loop to iterate through each data entry and execute the update query for each entry efficiently. 

// Assume $dataEntries is an array of data entries to update
// Assume $conn is the database connection object

// Prepare the update query
$stmt = $conn->prepare("UPDATE table_name SET column1 = :value1, column2 = :value2 WHERE id = :id");

// Iterate through each data entry and execute the update query
foreach($dataEntries as $entry) {
    $stmt->execute([
        'value1' => $entry['value1'],
        'value2' => $entry['value2'],
        'id' => $entry['id']
    ]);
}
