What are the differences between using the "improved" and "old" MySQL standards in PHP for database operations?

When performing database operations in PHP with MySQL, using the "improved" MySQL standards (i.e., MySQLi or PDO) is recommended over the "old" MySQL functions due to better security, performance, and support for modern MySQL features. To switch to the improved standards, you can simply update your database connection and query execution code to use MySQLi or PDO functions instead of the old MySQL functions. 

// Using MySQLi
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Example query
$sql = "SELECT * FROM table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data
    while($row = $result->fetch_assoc()) {
        echo "Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
