php - 从对象值到一个数组

Question

我有一个对象值

foreach($this->promo_cart->contents() as $produks){
    foreach($this->login_sess->contents() as $val):
        $idex = array_unique(explode('_', $produks['prod_name']));
        if($val['id']==$idex[2]) {
            echo $val[id]; //result is 314314315
        }
    endforeach;
}

我如何根据该结果制作一个数组，例如

array
(
  [0] => 314
  [1] => 314
  [2] => 315
)

Answer 1

您可以像这样将元素添加到数组中：

$foo = array(); // start with empty array
$foo[] = 'bar'; // added element to array => array([0] => "bar")

所以在你的情况下，你可以这样做：

$my_array = array();

foreach($this->promo_cart->contents() as $produks)
{
  foreach($this->login_sess->contents() as $val)
  {
    $idex = array_unique(explode('_', $produks['prod_name']));

    if($val['id']==$idex[2]) {
      $my_array[] = $val[id];
    }
  }
}

$my_array将包含：

array
(
  [0] => 314
  [1] => 314
  [2] => 315
)

[] 尝试创建新数组并将所需的值推送到该数组

 $tempArray=array();  //<---create new array
 foreach($this->promo_cart->contents() as $produks){
     foreach($this->login_sess->contents() as $val):
    $idex = array_unique(explode('_', $produks['prod_name']));
    if($val['id']==$idex[2]) {
        $tempArray[] = $val[id];  //<----push value to array.
    }
     endforeach;
  }
  print_r($tempArray);
