What are some best practices for updating multiple database entries in PHP?

When updating multiple database entries in PHP, it is best practice to use prepared statements to prevent SQL injection attacks and to improve performance by reducing the number of queries sent to the database. This can be achieved by looping through the entries and executing a single prepared statement for each update. 

// Assume $entries is an array of entries to be updated
// Assume $connection is a valid database connection object

// Prepare the update query
$stmt = $connection->prepare("UPDATE table_name SET column1 = ?, column2 = ? WHERE id = ?");

// Loop through each entry and execute the update query
foreach ($entries as $entry) {
    $stmt->bind_param("ssi", $entry['column1'], $entry['column2'], $entry['id']);
    $stmt->execute();
}

// Close the statement and connection
$stmt->close();
$connection->close();
