What is the significance of RLS (Row Level Security) in database management when it comes to user permissions and access control?

RLS is significant in database management as it allows for fine-grained control over user permissions by restricting access to specific rows in a table based on certain criteria. This helps in ensuring data security and confidentiality by only allowing users to see the data that they are authorized to access. 

// Implementing Row Level Security in PHP

// Assuming $userId contains the current user's ID

// Query to retrieve data based on user's permissions
$query = "SELECT * FROM table_name WHERE user_id = $userId";

// Execute the query and fetch the results
$result = mysqli_query($connection, $query);

// Use the fetched data as needed
while($row = mysqli_fetch_assoc($result)) {
   // Process the data
}
