forEach mongodb PHP -

is there efficient way use foreach in mongodb php, problem able add new row csv file every element in result array. 1 of possible solution use

$data mongo cursor

    $records = iterator_to_array($data);     $file = fopen("contacts.csv","w");     foreach ($records $record){                     fputcsv($file,$record);     } 

but, loading entire data memory not scalable option problem, data can huge.is there better alternative way able use foreach. how use foreach mongo php

$file = fopen("contacts.csv","w"); foreach ($data $record){                 $contact = iterator_to_array($record);         fputcsv($file,$contact); } 

this solution works $data remains cursor , iterator_to_array() inside loop converts individual record array placed in csv file.
