What are the best practices for transitioning from deprecated MySQL functions to MySQLi functions in PHP?

To transition from deprecated MySQL functions to MySQLi functions in PHP, you should update your code to use MySQLi functions for database operations. This involves replacing functions like mysql_connect, mysql_query, and mysql_fetch_array with their MySQLi equivalents like mysqli_connect, mysqli_query, and mysqli_fetch_array. Additionally, make sure to handle errors and exceptions properly when using MySQLi functions. 

// Deprecated MySQL functions
$connection = mysql_connect('localhost', 'username', 'password');
$result = mysql_query('SELECT * FROM table');
while ($row = mysql_fetch_array($result)) {
    // Process data
}

// Updated MySQLi functions
$connection = mysqli_connect('localhost', 'username', 'password');
$result = mysqli_query($connection, 'SELECT * FROM table');
while ($row = mysqli_fetch_array($result)) {
    // Process data
}
