Question

我试图在PHP中循环一个数组并提取一些值。我在获取以下数组的值时遇到困难：(702,car,707,car2,704car3...)

这就是我的数组的样子：

[data:protected] => Array (
  [0] => Array (
    [0] => 702
    [1] => car
  )
  [1] => Array (
    [0] => 707
    [1] => car2
  )
  [2] => Array (
    [0] => 704
    [1] => car3
  )
  [3] => Array (
    [0] => 705
    [1] => car4
  )
  [4] => Array (
    [0] => 708
    [1] => car5
  )
  [5] => Array (
    [0] => 709
    [1] => car6
  )
  [6] => Array (
    [0] => 706
    [1] => car7
  )
  [7] => Array (
    [0] => 703
    [1] => car8
  )
)

我试过这个：

foreach($result as $resultItem){
   $resultArray[] = $resultItem['n'];
}
print_r($resultArray);

但这只给了我一些价值观：

   Array ( [0] => 702 [1] => 707 [2] => 704 [3] => 705 [4] => 708 [5] => 709 [6] => 706 [7] => 703 )

如何访问其他值？

Answer 1

foreach($result as $resultItem) {
    foreach ($resultItem as $resultItemItem) {
        $resultArray[] = $resultItemItem;
    }
}

如果我看到你的阵列，这应该会很刺激。

Answer 2

假设数组的维度始终为2，您可以这样做

foreach($result as $resultItem)
{
    if(is_array($resultItem))
    {
        foreach($resultItem as $resultSubItem)
        {
            $resultArray[] = $resultSubItem;
        }
    }
    else $resultArray[] = $resultItem:
 }

如果数组的维度未知且您只想展平数组，请参阅此问题How to Flatten a Multidimensional Array?

$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($result));
foreach($it as $v) 
{
    $resultArray[] = $v;
}

Answer 3

试试这个

foreach($result as $resultItem){
   $resultArray[] = $resultItem[0];
   $resultArray[] = $resultItem[1];
}
print_r($resultArray);

Answer 4

foreach($result as $resultItem){
   $resultArray[] = array(
      $resultItem[0],
      $resultItem[1]
   );
}
print_r($resultArray);

你也可以这样做

foreach($result as $resultItem){
   $resultArray[$resultItem[0]] = $resultItem[1];
}
print_r($resultArray);

这样你的数组就像

数组（[701] =＆gt;＆＃39; car＆＃39;，[702] =＆gt;＆＃39; car＆＃39;，[703] =＆gt;＆＃39; car＆＃39;）

Answer 5

试试这段代码：

foreach($result as $resultItem){
   $resultArray = array_merge($resultArray,$resultItem);
}
