Array of String values, not an array of object Strings

Question

Basically I am calling an API to get an array of URLs for an image.

I start off by doing this

$mainResponse = array(
      "result" => array(
      ),
      "ack" => "success"
 );

I will then make my call and add the image URLs like this:

foreach($resp->Item as $item) {
  $picture = $item->PictureURL;
  array_push($mainResponse['result'], $picture);
}

Finally, I will echo this out to me.

 echo json_encode($mainResponse);

The problem I am facing is that my response is

{"result":[{"0":"IMAGE_URL","1":"IMAGE_URL"}],"ack":"success"}

Where I would want it to be like....

{"result":["IMAGE_URL","IMAGE_URL"],"ack":"success"}

Where did I go wrong in my PHP code?

Some codes are missed here. You can't convert array to object implicitly. But PictureURL property can be array of strings. Then you'll get this output. — u_mulder

ahhh @u_mulder you are right. i forgot to add that into there, but I did figure out the issue. If I do strval($pic) ill get the string value and not a set of objects. — letsCode

Seems like $picture is a associative array, change the foreach loop with this:

foreach($resp->Item->PictureURL as $item) {
 foreach($item as $_item){
  array_push($mainResponse['result'],$_item);}
}

This is not dynamic. Not a good answer at all. Not always will there be 2 pictures. There may be 1, 2, 3... n or even 0.

For some reason this API returns an object instead of an array. You can just do:

foreach ($resp->Item as $item) {
    $picture = $item->PictureURL;
    array_merge($mainResponse['result'], (array)$picture);
}

You can use array_push if you want every item to have separate pictures.
