将数组数组转换为一个数组

Question

I have a problem with my array, So my array is :

Array
(
   [0] => Array
    (
        [0] => Array
            (
                [sValue] => 1
            )

        [1] => Array
            (
                [sValue] => 2
            )

    )

) I want to get this array :

Array
(
  [0]=>1
  [1]=>2
)

I tried like this, but not work, it's get only the sValue = 1:

for($i=0;$i<count($aExpectedAnswers);$i++){
        foreach($aExpectedAnswers as $answer){
            $aFormatedAnswers[] = '\''.$answer[$i]['sValue'].'\'';
        }
    }

Help me please, Thx in advance
