我无法更改多维数组的键并分解其值

Question

我有一个数组：

Array ( [0] => Array ( [0] => Array ( [creator] => a, b ) [1] => Array ( [creator] => c, d ) ) [1] => Array ( [0] => Array ( [creator] => e, f ) ) [2] => Array ( [0] => Array ( [creator] => g, h ) [1] => Array ( [creator] => i, j ) [2] => Array ( [creator] => k, l ) [3] => Array ( [creator] => m, n ) [4] => Array ( [creator] => o, p ) ) )

我想将其所有键的名称从 [creator] 更改为 [author]，并且必须将其项目分解为 [first]、[last]

所以期望的输出应该是：

Array ( [0] => Array ( [0] => Array ( [author] => [first] => a [last] => b ) [1] => Array ( [author] => [first] => c [last] => d ) ) [1] => Array ( [0] => Array ( [author] => [first] => e [last] => f ) ) [2] => Array ( [0] => Array ( [author] => [first] => g [last] => h ) [1] => Array ( [author] => [first] => i [last] => j ) [2] => Array ( [author] => [first] => k [last] => l ) [3] => Array ( [author] => [first] => m [last] => n ) [4] => Array ( [author] => [first] => o [last] => p ) ) )

我试过：

for($loop=0; $loop<sizeof($output); $loop++) {
     $authors[] = $output[$loop]['creators'];
}
$a123 = explode(', ', $authors);
foreach ($authors as $items) {
    foreach ($items as $k => $v) {
        $myarray[$k]['author'] = $v;
    }
}

谢谢

一种方法是遍历数组的每个项目，分解 creator 值，使用该数据创建新的 author 值，然后使用 unset() 删除旧 creator 值。

foreach($array AS $a => $b)
{
    foreach($b AS $c => $d)
    {
        $name = explode(', ', $d['creator']);
        $array[$a][$c]['author'] = array(
            'first' => $name[0],
            'last' => $name[1]
        );
        unset($array[$a][$c]['creator']);
    }
}

代码未经测试，但应该能表达想法。

I can't change keys of the multi-dimensional array and explode its values

php

key

explode
