如何从数组

Question

这是我要处理的数组。

  

数组（[0] =＆gt;数组（[checklist_id] =＆gt; 3 [order_id] =＆gt; [id] =＆gt; 1）   [1] =＆gt;数组（[checklist_id] =＆gt; 4 [order_id] =＆gt; [id] =＆gt; 2）[2] =＆gt;   数组（[checklist_id] =＆gt; 7 [order_id] =＆gt; 8,9,10,11,12 [id] =＆gt; 4））;

尝试array_push

后

$alreadyassingorder=array();
        foreach ($collection as  $checklistorder) {
            if($checklistorder['order_id'])
            {
             $order=explode(',', $checklistorder['order_id']);

             array_push($alreadyassingorder,$order);

            }
        }

输出

  

数组（[0] =＆gt;数组（[0] =＆gt; 1 [1] =＆gt; 2 [2] =＆gt; 3 [3] =＆gt; 4 [4] =＆gt; 5   [5] =＆gt; 6 [6] =＆gt; 7）[1] =＆gt;阵列（[0] =＆gt; 8 [1] =＆gt; 9 [2] =＆gt; 10 [3] =＆gt;   11 [4] =＆gt; 12））

我想要的输出

  

数组（[0] =＆gt; 1 [1] =＆gt; 2 [2] =＆gt; 3 [3] =＆gt; 4 [4] =＆gt; 5   [5] =＆gt; 6 [6] =＆gt; 7）[7] =＆gt; 8 [8] =＆gt; 9 [9] =＆gt; 10 [10] =＆gt;   11 [11] =＆gt; 12））

Answer 1

试试这样：

$alreadyassingorder=array();
        foreach ($collection as  $checklistorder) {
            if($checklistorder['order_id'])
            {
             $order=explode(',', $checklistorder['order_id']);
             foreach($order as $index=>$key):     
               array_push($alreadyassingorder,$key);
             endforeach;

            }
        }
