PHP自定义重组数组 - PHP custom regroup array

PHP custom regroup array

我想重新分组数组，但我有列和分组子数组的问题:
My Array:

[0] => Array
(
    [0] => 1393/03
    [1] => 5666562
    [2] => 5
)
[1] => Array
    (
        [0] => 1393/03
        [1] => 491380
        [2] => 6
    )
[2] => Array
    (
        [0] => 1393/03
        [1] => 4210423
        [2] => 30
    )
[3] => Array
    (
        [0] => 1393/03
        [1] => 351000
        [2] => 55
    )
[4] => Array
    (
        [0] => 1393/03
        [1] => 53000
        [2] => 60
    )
[5] => Array
    (
        [0] => 1393/02
        [1] => 15799573
        [2] => 5
    )
[6] => Array
    (
        [0] => 1393/02
        [1] => 1144313
        [2] => 6
    )
[7] => Array
    (
        [0] => 1393/02
        [1] => 12131004
        [2] => 30
    )
[8] => Array
    (
        [0] => 1393/02
        [1] => 39000
        [2] => 55
    )

Result:(必须是这样:)

[0] => Array
    (
        [Date] => 1393/03
        [5] => 5666562
        [6] => 491380
        [30] => 4210423
        [60] => 53000
    )
[1] => Array
    (
        [Date] => 1393/02
        [5] => 15799573
        [6] => 1144313
        [30] => 12131004
        [60] => 39000
    )

我试着用foreach arrays和参考样本做我自己围绕互联网和堆栈溢出，但我没有找到一个好的解决方案。

简单的foreach循环应该就足够了。考虑这个例子:

$new_values = array();
$values = array( array('1393/03', 5666562, 5), array('1393/03', 491380, 6), array('1393/03', 4210423, 30), array('1393/03', 351000, 55), array('1393/03', 53000, 60), array('1393/02', 15799573, 5), array('1393/02', 1144313, 6), array('1393/02', 12131004, 30), array('1393/02', 39000, 55),);
foreach($values as $key => $value) {
    $new_values[$value[0]]['Date'] = $value[0];
    $new_values[$value[0]][$value[2]] = $value[1];
}
$new_values = array_values($new_values);
echo "<pre>";
print_r($new_values);
echo "</pre>";
