How can PHP developers ensure that their scripts are secure and do not use outdated MySQL extensions?

PHP developers can ensure that their scripts are secure and do not use outdated MySQL extensions by using the MySQLi or PDO extensions instead. These extensions provide better security features and support for modern database operations. To switch from the outdated MySQL extension to MySQLi, developers can simply update their connection and query functions to use the MySQLi equivalents. 

// Using MySQLi extension to connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Query using MySQLi
$result = $mysqli->query("SELECT * FROM table");

// Fetch data
while ($row = $result->fetch_assoc()) {
    // Process data
}

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