变换数组

Question

我如何获得此阵列：

Array
(
    [0] => Array
        (
            [max] => 5
            [year] => 2007
        )

    [1] => Array
        (
            [max] => 6.05
            [year] => 2008
        )

    [2] => Array
        (
            [max] => 7
            [year] => 2009
        )

)

采用以下格式：

[year] => [max]

（对我的无知感到惭愧......其中一天）

Answer 1

$result = array();
foreach($array as $v) {
    $result[$v['year']] = $v['max'];
}

你去。

Answer 2

您需要遍历当前数组并将数据放入新数组中。

$result = array();
foreach($currenArray as $x) 
{
    $result[$x['year']] = $x['max'];
}

Answer 3

简单的方法？

$dest = array();
foreach ($src as $k => $v) {
  $dest[$v['year']] = $v['max'];
}
