How can the LIMIT clause in MySQL be utilized to optimize database queries in PHP applications?

The LIMIT clause in MySQL can be utilized to optimize database queries in PHP applications by limiting the number of results returned from a query. This can help reduce the amount of data that needs to be processed and transferred, resulting in improved performance and efficiency. 

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Query with LIMIT clause to retrieve only 10 results
$query = "SELECT * FROM table_name LIMIT 10";
$result = $mysqli->query($query);

// Process the results
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Output or process each row
    }
} else {
    echo "No results found.";
}

// Close the connection
$mysqli->close();
