我有一个相当简单的多维数组，我想显示某个数组索引的“名称”......

例如，假设我的值为 22，我希望能够显示“轮椅”。

当涉及到第二维时，我有点迷失了。

到目前为止我已经尝试过..

$result 是上面的多维数组。

$resulting_bits 是这个数组（它是动态构建的，最多可以有 40 个值）：

Array ( [0] => 23 [1] => 26 [2] => 33 )

这是我目前拥有的代码

foreach($resulting_bits as $val) {

echo $val;

echo "<br>";

$answer = ($result[$val]);

foreach($answer as $conditionname) {


print_r ($conditionname);
echo "<br>";
echo $conditionname[Name];
}

这给了我

Array ( [0] => 23 [1] => 26 [2] => 33 )
23
M50
MM50
M8388608
88388608
826
Special
SSpecial
S67108864
667108864
633
Maxi10str
MMaxi10str
M8589934592
88589934592
8

这对我来说似乎很奇怪......我如何只显示“名称”？

Answer 1

the second for loop is unnecessary! It is not an associative array at that point.

foreach($resulting_bits as $val) {

echo $val;

echo "<br>";

$answer = ($result[$val]);
$name = $answer['Name'];
echo $name;

}

I would personnaly just do:

foreach($resulting_bits as $val) {

   echo $result[$val]['Name'];

}
