Why is it recommended to avoid using deprecated functions like mysql_db_query in PHP scripts?

Deprecated functions like mysql_db_query are no longer supported in newer versions of PHP and may be removed in future releases. It is recommended to avoid using deprecated functions to ensure compatibility and security of your PHP scripts. To solve this issue, you should switch to using modern alternatives like MySQLi or PDO for database operations. 

// Connect to MySQL using MySQLi
$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();
