Why is it recommended to use mysqli instead of mysql_* functions in PHP?

It is recommended to use mysqli instead of mysql_* functions in PHP because the mysql_* functions are deprecated and no longer maintained as of PHP 5.5.0. Using mysqli provides better security, support for prepared statements, and improved performance. To solve this issue, you should update your code to use the mysqli functions for interacting with a MySQL database. 

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

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

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

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

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