Question

我有一个数组

阵（ [13802172] =＆gt;排列（ [0] =＆gt; 13802172 [1] =＆gt;回顾 [2] =＆gt; ACCESS HIRE NSW [3] =＆gt; ACCESS HIRE NSW PTY LTD [4] =＆gt; [5] =＆gt; [6] =＆gt;设备租赁＆amp;租赁服务，工具R [7] =＆gt; 5106206 [8] =＆gt; [9] =＆gt; 7394
）

[13802174] => Array
    (
        [0] => 13802174
        [1] => reviewed
        [2] => ACRON ROAD OSHC
        [3] => ACRON ROAD OUT OF SCHOOL
        [4] => 
        [5] => 
        [6] => CHILD CARE SERVICES
        [7] => 5122005
        [8] => 
        [9] => 8351
    )

）

通过脚本动态生成13802174和13802172。

现在我需要[13802172] [6]的值作为EQUIP RENTALS＆amp; LEASING SERVICES，TOOL R动态，数组键可以很多，我需要显示第6个索引值的所有键。

你能告诉我一个答案怎么做？

Answer 1

您只需遍历整个数组，然后询问第7个值（索引6）：

foreach($arr as $v) 
  printf("<pre>%s</pre>", $v[6]);

您还可以查看array_keys。

Answer 2

好的，所以你会有很多像这样的数组

[13802174] => Array
    (
        [0] => 13802174
        [1] => reviewed
        [2] => ACRON ROAD OSHC
        [3] => ACRON ROAD OUT OF SCHOOL
        [4] => 
        [5] => 
        [6] => CHILD CARE SERVICES
        [7] => 5122005
        [8] => 
        [9] => 8351
    )

我假设您已将每个分配给动态生成的数组。

你可以这样循环

foreach($dynamicallyGeneratedArrays as $key => $dynamicArray) {

    print $key.": ".$dynamicArray[6];
}

或者您可能想将其分配给新数组

$newArray = array();
foreach($dynamicallyGeneratedArrays as $key => $dynamicArray) {

    if(isset($dynamicArray[6]) {

        $newArray[$key] = $dynamicArray[6];
    }
}
