What potential issues could arise when retrieving the last 10 entries from a database using PHP?

One potential issue that could arise when retrieving the last 10 entries from a database using PHP is the lack of an ORDER BY clause in the SQL query, which could result in the entries being retrieved in a random order. To ensure that the entries are retrieved in the correct order, you should include an ORDER BY clause in the query to sort the entries by a specific column, such as a timestamp or an auto-incrementing ID. 

// Retrieve the last 10 entries from a database with an ORDER BY clause
$query = "SELECT * FROM table_name ORDER BY id DESC LIMIT 10";
$result = mysqli_query($connection, $query);

// Loop through the results
while ($row = mysqli_fetch_assoc($result)) {
    // Process each entry
}
