In what ways can the delegation of root-level database access be avoided in PHP scripts to enhance security measures?

To avoid delegating root-level database access in PHP scripts, it is recommended to use a dedicated database user with limited privileges instead. This user should only have the necessary permissions to perform the required database operations, such as SELECT, INSERT, UPDATE, and DELETE. By following the principle of least privilege, the risk of potential security vulnerabilities can be minimized. 

// Connect to the database using a dedicated user with limited privileges
$servername = "localhost";
$username = "db_user";
$password = "password";
$dbname = "my_database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
