没有任何标签，我用PHP解释，因为这是我从直觉中看到的东西：）

一旦我知道您的语言支持，我一定会编辑我的帖子。

<?php

$myarr = Array(
        0 => Array
            (
                'a' => 1,
                'b' => 0,
                'c' => 0,
                'd' => 0,
            ),
            1=> Array
            (
                'a' => 0,
                'b' => 1,
                'c' => 0,
                'd' => 0,
            ),

        2 => Array
            (
                'a' => 0,
                'b' => 0,
                'c' => 1,
                'd' => 0,
            ),

    );

foreach($myarr as &$qwe )
{
 foreach($qwe as $key => &$value)
{
if($value == 1 )
$value++;
}
}

print_r($myarr);

<强>输出

Array
(
    [0] => Array
        (
            [a] => 2
            [b] => 0
            [c] => 0
            [d] => 0
        )

    [1] => Array
        (
            [a] => 0
            [b] => 2
            [c] => 0
            [d] => 0
        )

    [2] => Array
        (
            [a] => 0
            [b] => 0
            [c] => 2
            [d] => 0
        )

)
