How can PHP developers effectively manage image IDs and references when updating images within a database to ensure accurate updates?

When updating images within a database, PHP developers can effectively manage image IDs and references by ensuring that the correct image is being updated based on its unique identifier. This can be achieved by retrieving the image ID from the database before updating the image, and then using that ID to reference the correct image when performing the update.

// Retrieve image ID from database
$image_id = $_POST['image_id'];

// Update image in the database using the retrieved image ID
$query = "UPDATE images SET image_url = '$new_image_url' WHERE id = $image_id";
$result = mysqli_query($connection, $query);

if($result) {
    echo "Image updated successfully";
} else {
    echo "Error updating image";
}
