How can PHP developers ensure that their queries return the desired results when dealing with multiple entries in a database table?

When dealing with multiple entries in a database table, PHP developers can ensure that their queries return the desired results by using proper filtering and sorting techniques. One way to achieve this is by using SQL clauses such as WHERE, ORDER BY, and LIMIT to narrow down the results and ensure that they are displayed in the correct order. 

// Example of a PHP query with filtering and sorting
$query = "SELECT * FROM table_name WHERE condition ORDER BY column_name DESC LIMIT 10";
$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    while($row = mysqli_fetch_assoc($result)) {
        // Process the retrieved data
    }
} else {
    echo "No results found.";
}
