CodeIgniter Active Record: Load One Row at a Time

codeigniter, lazy-loading, mysqli, php

Solution

Here is something you can do.

while ($row = $result->_fetch_object()) {
  $data = array(
    'id'         => $row->id
    'some_value' => $row->some_field_name
  );
  // send row data to whatever api
  $this->send_data_to_api($data);
}

This will get one row at the time. Check the CodeIgniter source code, and you will see that they will do this when you execute the result() method.

Problem

The normal `result()` method described in the documentation appears to load all records immediately. My application needs to load about 30,000 rows, and one at a time, submit them to a third-party search index API. Obviously loading everything into memory at once doesn't work well (errors out because of too much memory). So my question is, how can I achieve the effect of the conventional MySQLi API method, in which you load one row at a time in a loop?
