• How to combine array of array values into one array? 4 answers

I want to merge an array with the current output as shown below to the expected output.

I was using a function array_reduce($currentArray, 'array_merge', array()); and it was working perfectly fine. But it doesnt seem to work now.

Current Output:

Array 
(
    [0] => Array
        (
            [0] => Array(...), 
            [1] => Array(...), 
            [2] => Array(...), 
        )
    [1] => Array
        (
            [0] => Array(...), 
            [1] => Array(...), 
            [2] => Array(...), "
        )
)

Expected Output:

Array 
(

            [0] => Array(...), 
            [1] => Array(...), 
            [2] => Array(...), 
            [3] => Array(...), 
            [4] => Array(...), 
            [5] => Array(...), 

)

function array_flatten($array) { 
      if (!is_array($array)) { 
        return FALSE;
      } 
      $result = array(); 
      foreach ($array as $key => $value) { 
        if (is_array($value)) { 
          $result = array_merge($result, array_flatten($value)); 
        } 
        else { 
          $result[$key] = $value; 
        } 
      } 
      return $result; 
    }
