How can the use of arrays in PHP be optimized to ensure accurate and distinct calculations for each database row in a loop?

When working with arrays in PHP to perform calculations on database rows in a loop, it's important to ensure that each calculation is done accurately and distinctly for each row. One way to optimize this is by resetting the array after each iteration of the loop to avoid carrying over values from previous iterations. This can be achieved by reinitializing the array within the loop before performing calculations on the current row. 

// Sample code snippet demonstrating how to optimize array calculations in a loop
$databaseRows = [/* array of database rows */];

foreach ($databaseRows as $row) {
    $tempArray = []; // Reset the temporary array for each row

    // Perform calculations on the current row using $tempArray
    // Add the calculated values to the $tempArray

    // Output the final calculations for the current row
    var_dump($tempArray);
}
