变换数组

Question

我如何获得这个数组:

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

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

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

)

进入这种格式:

[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'];
}

你去吧
