How can PHP users adapt their code to work with PHP 7.2, mysqli_query, and mysqli_error?

PHP users can adapt their code to work with PHP 7.2 by updating their code to use the mysqli_query function instead of the deprecated mysql_query function. They should also use mysqli_error to handle errors instead of mysql_error. This will ensure compatibility with PHP 7.2 and improve the security and performance of their code. 

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

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

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

if ($result) {
    // Process the result
} else {
    // Handle the error
    echo "Error: " . $mysqli->error;
}

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