Allowed memory size of 134217728 bytes exhausted (tried to allocate 31989760 bytes) In a do...while loop

Question

I have a do while code that reaches to an API to get data from AWS Elastic search. When I increase size, I get memory error. Now I have reduced size to 20, but want to loop through the results as a cronjob yet, it fails. I have increased memory to 4096 yet, it fails

I have increased memory limit in my .ini file, yet it fails. Since its a cronjob, I have no idea how to use scroll.

do {
  $transporter  = new TransporterController;
  $response = $transporter->dispatchSearch($paper->title, '55%', $size, $from, $rounds );
  $json_response = json_decode((string) $response->getBody(), true);
  $rounds = $json_response['rounds'];
  $from = $json_response['from'] + $json_response['size'];

  $response = $transporter->purify($response, $object);
  $impact_user_id = $paper->impact_user_id;
  $impact_type_id = 2;
  $response = $transporter->saveResult($response, $impact_user_id, $impact_type_id);
  $transporter->notifier($response, $user);
} while ($rounds > 1);

The idea is for the loop to run to completion, until last page. This is a laravel cronjob.

chances are your loop is going on forever. Have you tried debugging the `$json_response['rounds']` value? — Jerodev, Jan 07 '19 at 09:17
Yes, I have restructured the code to avoid using the loop. I save the last page to the database and query again using the last page as starting interval. — Ujah Jideofor, Jan 08 '19 at 10:05

Here are three methods to increase the limit on shared hosting:

Just add this below line to before line of you getting error in your file
```
 ini_set('memory_limit', '-1');
```
If you have access to your PHP.ini file, change the line in PHP.ini If your line shows 32M try 64M: memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)
If you don't have access to PHP.ini try adding this to an .htaccess file: php_value memory_limit 64M

Also make sure your file pointer is valid, and pass "r" (= reading) for mode.

I would be careful about changing the memory_limit without ensuring that optimization is what is needed. – Oluwatobi Samuel Omisakin Jan 07 '19 at 10:10
I have restructured the code to avoid using a loop. I save the last page to the database, at at interval, run cronjob to fetch using the last page as a starting point. Thank You – Ujah Jideofor Jan 08 '19 at 10:04
Whereas your solution works, I get a too many request error. Hence, the decision to do away with the loop. I have found a better alternative. Thank you. – Ujah Jideofor Jan 08 '19 at 10:06
where to add it ? – Moeez Dec 04 '19 at 10:55
In PHP.ini file – Madhuri Patel Dec 06 '19 at 04:59
