What are the advantages and disadvantages of using a database versus file handling for storing and manipulating data in PHP?

Using a database for storing and manipulating data in PHP offers advantages such as better organization, easier querying and searching, and improved data integrity through constraints and relationships. However, databases can be more complex to set up and maintain compared to file handling. File handling may be simpler for small amounts of data but can become inefficient and difficult to manage as data grows. 

// Example of connecting to a MySQL database in PHP
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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