What are the best practices for transitioning from mysql functions to mysqli functions in PHP code?

When transitioning from mysql functions to mysqli functions in PHP code, it is important to update the function calls and handle database connections properly. This involves changing functions like mysql_connect to mysqli_connect, mysql_query to mysqli_query, and so on. Additionally, make sure to update error handling and parameter binding to improve security and performance. 

// Before transitioning from mysql functions to mysqli functions
$conn = mysql_connect('localhost', 'username', 'password');
mysql_select_db('database', $conn);
$result = mysql_query('SELECT * FROM table', $conn);
while($row = mysql_fetch_assoc($result)) {
    echo $row['column'];
}
mysql_close($conn);

// After transitioning to mysqli functions
$conn = mysqli_connect('localhost', 'username', 'password', 'database');
$result = mysqli_query($conn, 'SELECT * FROM table');
while($row = mysqli_fetch_assoc($result)) {
    echo $row['column'];
}
mysqli_close($conn);
