What are best practices for building loops in PHP to update database entries efficiently?

When updating multiple database entries in PHP, it is best to use prepared statements within a loop to efficiently update each entry without the need to open and close a new database connection for each update. This helps reduce overhead and improve performance when updating a large number of entries. 

// Assume $db is your database connection

// Prepare the update statement outside the loop
$stmt = $db->prepare("UPDATE table SET column = :value WHERE id = :id");

foreach ($entries as $entry) {
    // Bind parameters and execute the statement within the loop
    $stmt->bindParam(':value', $entry['value']);
    $stmt->bindParam(':id', $entry['id']);
    $stmt->execute();
}

// Close the statement after the loop
$stmt->close();
