array_push not working for integers?

Question

I'm using array_push method to get all the integers into array as follows.

$response = json_decode($jsonResponse);
 foreach($response as $item) { //foreach element in $response
     $type = $item; 
     $unique_id = $type->id;
     $id_array=array();
     array_push($id_array, $unique_id);     
 }  
 var_dump($id_array);

But the $id_array contains only last integer element. Is there any wrong with above code or can't we push integer elements into php array?

You are resetting the array by initializing it in the loop. Take it out of the loop — Rishi

Put $id_array=array(); at the beginning of foreach

$response = json_decode($jsonResponse);
  $id_array=array();
  foreach($response as $item) { //foreach element in $response
      $type = $item; 
      $unique_id = $type->id;
      array_push($id_array, $unique_id);     
  }  
 var_dump($id_array);

You can Minimize Code inside foreach

$response = json_decode($jsonResponse);
$id_array=array();
foreach($response as $item) { //foreach element in $response
    $unique_id = $item->id;
    array_push($id_array, $unique_id);     
}  
var_dump($id_array);

OR

$response = json_decode($jsonResponse);
$id_array=array();
foreach($response as $item) { //foreach element in $response
  array_push($id_array, $item->id);     
}  
var_dump($id_array);

Or it's just array_push($id_array, $item->id);

Initialize the array outside the loop :

$response = json_decode($jsonResponse);
$id_array = array();
foreach($response as $item) { //foreach element in $response
    $type = $item; 
    $unique_id = $type->id;
    array_push($id_array, $unique_id);     
}

$response = json_decode($jsonResponse);
$id_array=array();
foreach($response as $item) { //foreach element in $response
   $type = $item; 
   $unique_id = $type->id;
   array_push($id_array, $unique_id);     
}  
var_dump($id_array);

This should work..
