Question

我有一个我从MySQL查询创建的php关联数组。它看起来像这样;

        array(
                (int) 0 => array(
                        'items' => array(
                                'index_no' => '1'
                        ),
                        (int) 0 => array(
                                'NumItems' => '2'
                        )
                ),
                (int) 1 => array(
                        'items' => array(
                                'index_no' => '2'
                        ),
                        (int) 0 => array(
                                'NumItems' => '3'
                        )
                )

看起来不必要的复杂。我想简化它看起来像这样;

        array(
                (int) 0 => array(
                                'index_no' => '1',
                                'NumItems' => '2'
                        )
                ),
                (int) 1 => array(
                                'index_no' => '2',
                                'NumItems' => '3'
                        )
                )

如何在php中完成？我一直坚持这个问题。如果我有，我会发布我的答案。如果有人能给我一些起点，我将不胜感激。非常感谢你。

Answer 1

你可以尝试一下：

$tempArray = array(
                (int) 0 => array(
                        'items' => array(
                                'index_no' => '1'
                        ),
                        (int) 0 => array(
                                'NumItems' => '2'
                        )
                ),
                (int) 1 => array(
                        'items' => array(
                                'index_no' => '2'
                        ),
                        (int) 0 => array(
                                'NumItems' => '3'
                        )
                ));

$newArray = array();
$i=0;
foreach($tempArray as $temp) {
    $newArray[$i]['index_no'] = $temp['items']['index_no'];
    $newArray[$i]['NumItems'] = $temp[0]['NumItems'];
    $i++;
}
print "<pre>";
print_r($newArray);

Answer 2

试试这个

<?php $res=array(array('item'=>1,'number'=>5),array('item'=>2,'number'=>56));
 $final_array =array();
 $i=0;
  foreach ($res as $val)
  {
     foreach($val as $key=>$val2)
     {
      $final_array[$i][$key] = $val2;

      }$i++;
    }

  print_r($final_array);
   ?>

Answer 3

这是你的解决方案。

$diffArray = array(
    (int) 0 => array(
        'items' => array(
            'index_no' => '1'
        ),
        (int) 0 => array(
            'NumItems' => '2'
        )
    ),
    (int) 1 => array(
        'items' => array(
            'index_no' => '2'
        ),
        (int) 0 => array(
            'NumItems' => '3'
        )
        ));

print_r($diffArray);

$getArray = array();
foreach ($diffArray as $simArray) {

    $getArray['index_no'][] = $simArray['items']['index_no'];
    $getArray['NumItems'][]= $simArray[0]['NumItems'];
}
print_r($getArray);

Answer 4

$newArray = array();
foreach ($array as $items) {
    $temp = array('index_no' => $items['index_no']);
    $temp = array_merge($temp, $items[0]);
    $newArray[] = $temp;
}

它会将所有键添加到index - 0

下的数组中

如何在php中删除不必要的信息并重构这个关联数组？
