What is the current status of the mysqli_ function in PHP and what are the alternatives?

The mysqli_ function in PHP is currently deprecated as of PHP 5.5.0 and will be removed in future versions of PHP. It is recommended to switch to the object-oriented MySQLi or PDO extension for database operations in PHP.

// Using MySQLi Object-oriented approach
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Perform database operations using $mysqli object

$mysqli->close();
