skip n rows of csv file in php -

i have csv file have 500000 number of rows. need take first 100 rows in first loop , manipulate rows (say, send first 100 ids api , save response). in second loop, skip first 100 rows(already taken) , take 100 rows , send request web service. similarly, in third loop, skip first 200 rows , take 100 rows , send request web service , on...

i can take single each rows below code. (tested : works great)

if (($handle = fopen($filename, "r")) !== false) {     $id   = 1;     $line = fgetcsv($handle); //skip first row      //fetch data each row     while (($data = fgetcsv($handle, ",")) !== false) {         $hotel_id   = $data[0];         //call service request web service         $hoteldetailrequest = (new \services\hotel\hotel)->gethotelstaticdata($hotel_id);         //do stuff response     } } 

similarly, can skip initial rows skipped first row adding

$line = fgetcsv($handle); $line = fgetcsv($handle); $line = fgetcsv($handle); 

but, not expected result explained above. using php(laravel). googled, not found suitable match criteria. has face same problem?

any appreciated. thank you

here solution you:

<?php $filename = "the_data.csv"; $chunk_size = 200;  // parse csv file array $csv_data = array_map('str_getcsv', file($filename));  // split data array chunks $chunked_data = array_chunk($csv_data, $chunk_size);  foreach($chunked_data $chunk){      // here have $chunk_size row data     // iterate in chunk     foreach($chunk $row ){         $hotel_id   = $row[0];          // send request web service         // stuff response     }      sleep(1); } ?>
