How can the use of the function `mysql_tablename()` impact the performance of a PHP application?

Using the `mysql_tablename()` function can impact the performance of a PHP application because it is deprecated and has been removed in newer versions of PHP. To solve this issue, you should use the `mysqli` or `PDO` extension for interacting with MySQL databases, as they provide more secure and efficient ways to work with databases. 

// Connect to MySQL using mysqli
$mysqli = new mysqli('localhost', 'username', 'password', 'database');

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

// Use mysqli query to get table names
$query = "SHOW TABLES";
$result = $mysqli->query($query);

// Fetch table names
while ($row = $result->fetch_array()) {
    echo $row[0] . "<br>";
}

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