What is the significance of using a Modulo operation in PHP when retrieving specific rows from a database?

Using a Modulo operation in PHP when retrieving specific rows from a database can be significant when you want to evenly distribute the selection of rows based on a certain criterion. For example, if you want to select every nth row from a database table, you can use the Modulo operation to achieve this. This can be useful for implementing pagination or displaying data in a specific order. 

// Retrieve every 5th row from a database table using Modulo operation
$query = "SELECT * FROM table_name";
$result = mysqli_query($connection, $query);

$count = 0;
while ($row = mysqli_fetch_assoc($result)) {
    if ($count % 5 == 0) {
        // Process or display the row here
    }
    $count++;
}
