PHPタグなしで、これが私の直感から私に見えるものであるため、説明しています:)

あなたの言語サポートがわかったら、必ず投稿を編集します。

<?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);
