I am using PHP Codeigniter. I have a result from model as

Array ( [0] => stdClass Object ( [player_id] => 5bbbdfb4-6986-4383-90af-e3a12782b572 ) [1] => stdClass Object ( [player_id] => 46834ecd-ceef-49b8-a10a-706ee97ff729 ) )

I want to convert into 

array("5bbbdfb4-6986-4383-90af-e3a12782b572","46834ecd-ceef-49b8-a10a-706ee97ff729")

I am breaking my head for 2 day on this. Any help appreciated.

  • Not sure of a CI specific way, but PHP 7+ you should be able to do `array_column($array, "player_id")` – Nigel Ren Oct 21 '19 at 07:21
  • Use ``typecasting``like this $new_array = (array)$my_objects; – Lets-c-codeigniter Oct 21 '19 at 07:23
  • I have used `array_column($array, "player_id")`, Where the output is `Array ( [0] => 5bbbdfb4-6986-4383-90af-e3a12782b572 [1] => 46834ecd-ceef-49b8-a10a-706ee97ff729 )` – Stephen Paulraj Oct 21 '19 at 07:23
  • i suspect you get your results from a database ? if you use `$query->result()` you can als use `$query->result_array()` – Atural Oct 21 '19 at 07:27
  • Try using json_encode() method to convert it into json format. Also edit your question and add the code you are writing and getting this result. – Ramsha Omer Oct 21 '19 at 07:41

You can try use this:

$arr = json_decode(json_encode($arr_obj), True);

also as 

$arr = (array)$arr_obj;

You can use array_column in PHP 7+ as said by Nigen Sen.

You can also use following function too

$players = array_map(function($e) {
    return $e->player_id;
}, $records); // $records is your array object that need to be processed.

print_r( $players );

  • Thanks Vantiya, as yours and Nigen Sen's suggestion both returns `Array ( [0] => 5bbbdfb4-6986-4383-90af-e3a12782b572 [1] => 46834ecd-ceef-49b8-a10a-706ee97ff729 )` how to convert again to `array("5bbbdfb4-6986-4383-90af-e3a12782b572", "46834ecd-ceef-49b8-a10a-706ee97ff729")` – Stephen Paulraj Oct 21 '19 at 07:35
  • @StephenPaulraj, do you know that `Array([0] => 'www')` is equal to `Array('www')`? – Aksen P Oct 21 '19 at 07:37

    It's an array. each elements in array if you declare like array("5bbbdfb4-6986-4383-90af-e3a12782b572", "46834ecd-ceef-49b8-a10a-706ee97ff729") has it's default index starting from zero. It's a characteristics of an array. – Vantiya Oct 21 '19 at 07:38
  • An array is simply a variable that stores data of similar type with index/key. – Vantiya Oct 21 '19 at 07:39
  • @asken-p I do know that, I am passing the same to result to Onesignal i get the error. The acceptable key was `array("x","y","z")`, 'Array('www')' this is not going by. – Stephen Paulraj Oct 21 '19 at 07:55
