>我的嵌套结构与文件夹结构非常相似，例如：
Array
(
[level_one_1] => Array
(
[level_two_1] => value1
[level_two_2] => valuetwo
[level_two_3] => value_three
)
[level_one_2] => Array
(
[level_two_4] => value1
[level_two_5] => valuetwo
[level_two_6] => value_three
)
[level_one_3] => Array
(
[level_two_2] => valuetwo
[level_two_3] => value_three
)
)
这是一种快速将其隐藏为这样的方法：
Array
(
[level_one_1/level_two_1] => value1
[level_one_1/level_two_2] => valuetwo
[level_one_1/level_two_3] => value_three
[level_one_2/level_two_4] => value1
[level_one_2/level_two_5] => valuetwo
[level_one_2/level_two_6] => value_three)
[level_one_3/level_two_2] => valuetwo
[level_one_3/level_two_3] => value_three
)
级别之间的斜杠将是分隔符 - 它可以是任何东西。此外，它将是动态的级别数。
这是一种通过使用预定义的数组*函数来做到这一点的方法吗？ 递归 ？
像这样的东西。未经测试，但应该可以帮助您朝着正确的方向开始：
$myArray = array(
'level_one_1' => array(
'level_two_1' => 'value1',
'level_two_2' => 'valuetwo',
'level_two_3' => 'value_three'
),
'level_one_2' => array(
'level_two_4' => 'value1',
'level_two_5' => 'valuetwo',
'level_two_6' => 'value_three'
),
'level_one_3' => array(
'level_two_2' => 'valuetwo',
'level_two_3' => 'value_three'
));
$ritit = new RecursiveIteratorIterator(new RecursiveArrayIterator($myArray));
$result = array();
foreach ($ritit as $leafValue) {
$keys = array();
foreach (range(0, $ritit->getDepth()) as $depth) {
$keys[] = $ritit->getSubIterator($depth)->key();
}
$result[ join('/', $keys) ] = $leafValue;
}
