I've encountered the following problem:

private function getMyThemeIds($collection){
    $result = [];
    ...
      foreach ($results as $doc) {
        file_put_contents('2.txt', $doc->getUnid()); //everything is fine here

        $result[] = $doc->getUnid();

        file_put_contents('3.txt', print_r($result,true)); //again, array is just fine, barely 4000 entries
      }

    file_put_contents('4.txt', print_r($result,true)); // but here we see what was in this array right after initialization. Nothing in this case.
    return $result;
  }

I've tried different approaches - changed foreach to for, $result[] to array_push, etc with no avail. Anybody knows what the cause of this may be?

where id your $results ?? – Rahautos Oct 21 at 6:19
    
Not sure but you can use like $result = array(); for $result = []; while declaration.. – Maha Dev Oct 21 at 6:22
    
What is your php version? If you are below php-5.4 than change $result = []; to $result = array(); – Chayan Oct 21 at 6:24
    
Does $doc->getUnid(); prints proper output? It must not return empty. – sandeepsure Oct 21 at 6:27
    
@Rahautos, beyond that "..." – Moorindal Oct 21 at 6:27

You can initialize array using 'array()'.Please follow below statment to initialize array

$result = array();

After initialize $result you can append data to it. You can refer following link for array initialization- http://www.w3schools.com/php/func_array.asp

Variable was initialized with $result = []; as of php-5.4 – Chayan Oct 21 at 6:43
    
Somehow... It worked. I can swear I already tried this! Well, thanks everybody. – Moorindal Oct 21 at 6:47
    
array_push($result,$doc->getUnid()); – WisdmLabs Oct 21 at 6:47

Please see the file_put_contents for details. You can try this.

private function getMyThemeIds($collection){
    $result = array();
    ...
      foreach ($results as $doc) {
        file_put_contents('2.txt', $doc->getUnid()); //everything is fine here

        $result[] = $doc->getUnid();

        file_put_contents('3.txt', serialize($result)); //again, array is just fine, barely 4000 entries
      }

    file_put_contents('4.txt', serialize($result)); // but here we see what was in this array right after initialization. Nothing in this case.
    return $result;
  }
