将数组数组转换为一个数组

Question

我的数组有问题，所以我的数组是：

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

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

    )

） 我想得到这个数组：

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

我试过这样，但不行，它只得到sValue = 1：

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

请提前帮助我

Answer 1

$aFormatedAnswers = [];
      foreach ($aExpectedAnswers as $answer) {
          if (is_array($answer)) {
             foreach ($answer as $item) {
              $aFormatedAnswers[] = $item;
              }
          } else {
           $aFormatedAnswers[] = $answer;
        } 

Answer 2

$result = array();
foreach($initial as $subArray){
    foreach($subArrray as $value){
        $result[] = $value;
    }
}
print_r($result);

Answer 3

试试这段代码：

$aExpectedAnswers = array(
    array(
     0 => array('sValue'=>1),
     1 => array('sValue'=>2),
    )
);

$result = array();
foreach($aExpectedAnswers as $aea){
    foreach($aea as $ae){
        $result[] = $ae['sValue'];
    }
}

print_r($result);

希望有所帮助。
