What are the best practices for iterating through MySQL query results in PHP to ensure accurate data display?

When iterating through MySQL query results in PHP, it is important to use the appropriate fetching method based on the query type (e.g., SELECT, INSERT, UPDATE). For SELECT queries, use a loop to fetch each row of data until there are no more results. Make sure to properly handle errors and close the connection after fetching all results to ensure accurate data display. 

// Assuming $conn is the MySQL connection object and $query is the SQL query
$result = mysqli_query($conn, $query);

if ($result) {
    while ($row = mysqli_fetch_assoc($result)) {
        // Process each row of data here
        echo $row['column_name'] . '<br>';
    }
    
    // Free result set
    mysqli_free_result($result);
} else {
    // Handle query errors
    echo 'Error: ' . mysqli_error($conn);
}

// Close connection
mysqli_close($conn);
