What are the potential benefits of using a "SELECT in SELECT" approach in SQL queries for data manipulation in PHP?

When dealing with complex data manipulation tasks in PHP using SQL queries, using a "SELECT in SELECT" approach can be beneficial for scenarios where you need to retrieve data based on dynamic conditions or aggregate functions. This approach allows you to nest SELECT statements within each other to filter, group, or manipulate data in a more flexible and efficient manner. 

// Example of using a "SELECT in SELECT" approach in PHP for data manipulation
$query = "SELECT * FROM table WHERE column IN (SELECT column FROM another_table WHERE condition)";
$result = mysqli_query($connection, $query);

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