How can PHP developers efficiently handle data manipulation and calculations when dynamically removing records from a database query result set?

When dynamically removing records from a database query result set, PHP developers can efficiently handle data manipulation and calculations by reindexing the array after removing the desired records. This ensures that any subsequent calculations or data manipulations are accurately performed on the updated result set. 

// Assuming $result is the original database query result set
// Dynamically remove records based on certain conditions
foreach ($result as $key => $record) {
    if ($record['condition']) {
        unset($result[$key]);
    }
}

// Reindex the array after removing records
$result = array_values($result);

// Perform data manipulation and calculations on the updated result set
foreach ($result as $record) {
    // Perform calculations or data manipulation here
}
