Question

我有这样的数组而我想知道的是例如搜索此数组中的值9375，然后在此键中获取其他值。

Array
(
[0] => Array
    (
        [0] => Afghanistan
        [1] => 93
        [2] => 0.2
        [3] => 2015-06-09
    )

[1] => Array
    (
        [0] => Afghanistan Cdma Afghan Telecom
        [1] => 9375
        [2] => 0.22
        [3] => 2015-03-31
    )

[2] => Array
    (
        [0] => Afghanistan mobile
        [1] => 937
        [2] => 0.158
        [3] => 2015-03-31
    )

我试图获得这样的密钥，但它不起作用

$position = array_search('937', $array);

echo "<td>".$array[$position][0]."</td>";
echo "<td>".$array[$position][1]."</td>";
echo "<td>".$array[$position][2]."</td>";
echo "<td>".$array[$position][3]."</td>";

Answer 2

var qualificationIsDifferent = options.qualification_id !== this.activeId;
var isNotActive = this.hasOwnProperty('activeId') && qualificationIsDifferent;
var shouldDoStuff = !this.initialized || isNotActive;

if ( shouldDoStuff ) { ... }

array_filter非常适合获取大型数组并搜索它以返回仅包含与搜索匹配的值的新数组

$search = 9375;
$result = array_filter(
    $myArray,
    function ($value) use ($search) {
        return in_array($search, $value);
    }
);

如果您只在每个子阵列的第二个元素中查找搜索键：

$search = 9375;
$result = array_filter(
    $myArray,
    function ($value) use ($search) {
        return $value[1] == $search;
    }
);
