What are the potential pitfalls of using LIMIT and ORDER BY together in PHP queries?

When using LIMIT and ORDER BY together in PHP queries, it's important to note that the ORDER BY clause should come before the LIMIT clause in the query. If the ORDER BY clause is placed after the LIMIT clause, the results may not be ordered as expected. To avoid this pitfall, always ensure that the ORDER BY clause precedes the LIMIT clause in your SQL query. 

// Example of a correct query using LIMIT and ORDER BY
$sql = "SELECT * FROM table_name ORDER BY column_name LIMIT 10";
$result = mysqli_query($connection, $sql);

// Fetch and display results
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}
