What are the potential pitfalls of using mysqli_fetch_x to retrieve data from a MySQL table in PHP?

One potential pitfall of using mysqli_fetch_x to retrieve data from a MySQL table in PHP is that it can lead to errors or unexpected behavior if not used correctly. To avoid this, it is important to check for false values returned by mysqli_fetch_x functions to handle cases where there is no more data to fetch. 

$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

if($result){
    while($row = mysqli_fetch_assoc($result)){
        // Process the fetched data
    }
} else {
    echo "Error: " . mysqli_error($connection);
}
