Convert multidimensional array into single array

Question

I have an array which is multidimensional for no reason

/* This is how my array is currently */
Array
(
[0] => Array
    (
        [0] => Array
                


        

Answer 1

 $singleArray = array();

    foreach ($multiDimensionalArray as $key => $value){
        $singleArray[$key] = $value['plan'];
    }

this is best way to create a array from multiDimensionalArray array.

thanks

Answer 2

Despite that array_column will work nice here, in case you need to flatten any array no matter of it's internal structure you can use this array library to achieve it without ease:

$flattened = Arr::flatten($array);

which will produce exactly the array you want.

Answer 3

Just assign it to it's own first element:

$array = $array[0];

Answer 4

Assuming this array may or may not be redundantly nested and you're unsure of how deep it goes, this should flatten it for you:

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; 
} 

Answer 5

This simple code you can use

$array = array_column($array, 'value', 'key');

Answer 6

For this particular case, this'll do:

$array = array_map('current', $array[0]);

It's basically the exact same question is this one, look at some answers there: PHP array merge from unknown number of parameters.
