Adjust array format after converting from XML

I try to parse xml into arrays. I have got 2 types of incoming data: 1) 

<rows>
<item>
<a>A</a>
<b>B</b>
</item>
<item>
<c>C</c>
<d>D</d>
</item>
</rows>

2) 

<rows>
<item>
<e>E</e>
<f>F</f>
</item>
</rows>

I create an object of SimpleXMLElement and then convert it in array as in Converting a SimpleXML Object to an Array using first answer. The result in first case is 

[ '0' => ['a' => 'A', 'b' => 'B'], '1' => ['c' => 'C', 'd' => 'D']].

The result in second case is ['e' => 'E', 'f' => 'F']

But I need a numeric key in second case [ '0' => ['e' => 'E', 'f' => 'F']]

How to fix it?

For your given example, I think you could use array_values which (from the docs):

returns all the values from the array and indexes the array numerically.

$xml = simplexml_load_string($source);
$result = array_values(json_decode(json_encode($xml), true));
var_dump($result);

Will give you:

array(1) {
  [0]=>
  array(2) {
    ["e"]=>
    string(1) "E"
    ["f"]=>
    string(1) "F"
  }
}

If you have your e,f array (Which is the output of your second case, but i've generated it here. Just use your XML array from your second case)

$arr1 = array(
    'e' => 'E',
    'f' => 'F',
    'g' => 'G',
    'h' => 'H',
);

you can then do 

$arr2 = array_chunk($arr1, 2);

which will give you the output ($arr2):

[0 => ['e' => 'E', 'f' => 'F'], 1=> ['g' => 'G', 'h' => 'H']]

and that will work assuming that you want your sub arrays to always be 2 items in length. You can change that by changing the second parameter of array_chunk().
