merge array in single array

Question

I have used the following code to get array and merge them.
On the print_r(arr1) I get following array. In $arr I am trying to merge array but when i print_($arr) at the end of for-each I get same array.
Am I doing wrong array merge? How can i combine or merge it?

foreach($q1->result_array() as $row4)
 {  
        $arr1 = $q1->result_array();
        echo"<pre>"; 

            print_r($arr1); 

        echo"</pre>";
        $arr = array_merge($arr, $arr1);
        echo "<br/>";
        $id = $row4['id'];
        $parent_id = $row4['parent_id'];
        if(!empty($arr1))
        {
            $this->showreply($id);                          
        }

 }
 print_r($arr);

Array which i get on print_r($arr1):

Array
(
    [0] => Array
        (
            [id] => 69
            [reply] => First reply to Reply
            [parent_id] => 68
            [postid] => 0
            [us_id] => 41
            [added_by] => Shailesh

            [us_id] => 50
            [added_by] => swapnil
            [photo] =>

        )

$arr = array_merge($arr, $arr1);

This $arr variable was never initialized, so nothing plus $arr1 equals to $arr1.

Also why is this code inside a foreach?

:code inside foreach because each time i get new array and want to merge that in single array.

Naryl Over a year ago

but each time you get a different $row4 value, not a different $arr1!

try this...i think this is what you are looking for

    foreach($q1->result_array() as $row4)
    {  
         $arr1 = $q1->result_array();

          $arr[]=$row4; 
    }

  print_r($arr)
