我有一个包含许多嵌套子级别的多维数组，我想将其打印为格式良好的ol li ol li ...列表。所以我创建了这个函数，但它无法正常工作：
function loop($array) {
echo '<ol class="dd-list">';
$arrayObj = new ArrayObject($array);
foreach ( $iterator = $arrayObj->getIterator() as $key => $value ) {
if(is_array($value)) {
loop($iterator->current());
} else {
if($iterator->key()=='position') {
echo '<li class="dd-item" data-id="' . $iterator->current() . '">';
echo '<div class="dd-handle">' . $iterator->key() . ' ' . $iterator->current() . '</div>';
echo '</li>';
}
}
}
echo '</ol>';
}
我该如何解决？ 给定的数组是：
Array
(
[item] => Array
(
[0] => Array
(
[ID] => 22063
[position] => 1
[disegno] => Disegno 22063
[items] => Array
(
[item] => Array
(
[0] => Array
(
[ID] => 22315
[position] => 1.1
[disegno] => Disegno 22315
)
[1] => Array
(
[ID] => 22064
[position] => 1.2
[disegno] =>
Disegno 22064
)
[2] => Array
(
[ID] => 22065
[position] => 1.3
[disegno] =>
Disegno 22065
[items] => Array
(
[item] => Array
(
[0] => Array
(
[ID] => 22065_1
[position] => 1.3.1
[disegno] =>
Disegno 22065_1
)
[1] => Array
(
[ID] => 22065_2
[position] => 1.3.2
[disegno] =>
Disegno 22065_2
)
)
)
)
[3] => Array
(
[ID] => 22068
[position] => 1.4
[disegno] =>
Disegno 22068
)
)
)
)
[1] => Array
(
[ID] => 24728
[position] => 2
[disegno] =>
Disegno 24728
)
[2] => Array
(
[ID] => 445
[position] => 3
[disegno] =>
Disegno 445
)
[3] => Array
(
[ID] => 21318
[position] => 4
[disegno] =>
Disegno 21318
)
)
）

我没有把迭代器拿出来。也许我错过了一些东西，但它似乎过度复杂化了一个简单的问题。
另外，为了达到你想要的效果，在某些时候你必须给div的data-id属性一个数组，而不是一个值。我在下面的代码中更改了它，以便它接收密钥 - 但我想你应该改变它;
以下是代码：
function loop($array) {
echo '<ol class="dd-list">';
echo "\n";
foreach ( $array as $key => $value ) {
//this is the line I was talking about earlier
echo '<li class="dd-item" data-id="' . $key . '">';
if(is_array($value)) {
loop($value);
} else {
echo '<div class="dd-handle">' . $key . ' => ' . $value . '</div>';
}
echo '</li>';
echo "\n";
}
echo '</ol>';
}
$testArray = array('1', '2', array('3', '4'));
loop($testArray);
