What are the potential pitfalls of using the mysql_* extension in PHP for database backups?

Using the mysql_* extension in PHP for database backups is not recommended as it is deprecated and has been removed in newer versions of PHP. It is also vulnerable to SQL injection attacks. To solve this issue, it is recommended to use the mysqli or PDO extension for interacting with databases in PHP. 

// Using mysqli extension for connecting to database
$mysqli = new mysqli("localhost", "username", "password", "database_name");

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

// Perform database backup operations using mysqli
// Close the connection
$mysqli->close();
