Question

我有一个名为$ array的如下。我需要能够根据[day]值拉出其中的特定数组。

因此，例如，我可以将$ day2等于$ array [1]，因为它的日值是2，依此类推。我怎么能这样做呢？当它们进来时它们没有被排序，并且不能有倍数，因为$ array中的最大数组数量可以是7，因为一周有7天。

    [0] => Array
        (
            [time_id] => 1

            [day] => 1
            [12a] => 0

为任何感兴趣的人编辑：

这是我最终得到的结果...... $ settings是原始的多阵列...

//set counter
$counter = 0;

//loop through and set different day arrays
foreach($settings as $value) {
    // inc counter
    $counter++;

    //set array using variable variables ($hourstemp is actually $hours1, $hours2, $hours3, etc.)
    if($value['day'] == $counter) {
        $hourstemp = 'hours'.$counter;
        $$hourstemp = $value;
    }
}

Answer 1

如果您想获得特定日期：

$day = 2;

foreach($array as $value) {
    if($value['day'] == $day) {
         $result = $value;
         break;
    }
}

或者如果它们是一致的，那个'day'总是比索引大1，那么只需：

$result = $array[$day-1];

或者如果你想重新排序数组，那么索引就是'day'：

foreach($array as $value) {
    $result[$value['day']] = $value;
}
//then you can just use $result[$day]

从多个数组中保存特定的数组？
