Question

我有这三个子数组，我想制作一个数组在每个数组中搜索最高值，并放入其键进入另一个数组，创建一个新的键/键值数组

修改我正在查看所有0，然后全部1，然后全部2来找到那里的最高值。我想总是从所有时间最高数字开始，然后在键变为不可用时继续前进到最小

输入就是

Array
(
    Array
    (
        [0] => 16 
        [1] => 27 
        [2] => 36 // highest, 2 is now unavailable
    )
    Array
    (
        [0] => 27
        [1] => 13.5  // highest, 1 is now unavailable
        [2] => 9 
    )
    Array
    (
        [0] => 81 // highest, 0 is now unavailable
        [1] => 18
        [2] => 27 
    )
)

输出

Array
(
    [0] => [2]
    [1] => [1]
    [2] => [0]
)

Answer 1

如果我找对你的话，沿着这些方向应该做的事情：

$result = array();

foreach ($array as $numbers) {
    $highestKey = null;
    $highestNum = null;

    foreach ($numbers as $key => $value) {
        if ($value > $highestNum && !in_array($key, $result)) {
            list($highestKey, $highestNum) = array($key, $value);
        }
    }

    $result[] = $highestKey;
}

Answer 2

$results = array();
foreach ($array as $value) {
    arsort($value);
    $temp = array();        
    foreach ($value as $subkey => $subval) {
        if (!in_array($subkey, $results))
        $temp[] = $subkey;
    }       
    $results[] = $temp[0];
}
