在php中匹配数组

Question

我需要检查一个给定的数组是否与另一个数组匹配。我不知道如何操作第一个数组，或者以其他方式匹配它。

我需要匹配这个数组：

    Array
(
    [1] => site
    [2] => blog
    [3] => index.php
)

要与此匹配，请执行以下操作：

Array
(
    [site] => Array
        (
            [path] => site
            [name] => site
            [kind] => directory
            [content] => Array
                (
                    [404] => Array
                        (
                            [path] => site/404.php
                            [name] => 404.php
                            [extension] => php
                            [kind] => file
                        )

                    [blog] => Array
                        (
                            [path] => site/blog
                            [name] => blog
                            [kind] => directory
                            [content] => Array
                                (
                                    [contact] => Array
                                        (
                                            [path] => site/blog/contact.php
                                            [name] => contact.php
                                            [extension] => php
                                            [kind] => file
                                        )

                                    [index] => Array
                                        (
                                            [path] => site/blog/index.php
                                            [name] => index.php
                                            [extension] => php
                                            [kind] => file
                                        )

                                    [about] => Array
                                        (
                                            [path] => site/blog/about.php
                                            [name] => about.php
                                            [extension] => php
                                            [kind] => file
                                        )

                                )

                        )

                    [index] => Array
                        (
                            [path] => site/index.php
                            [name] => index.php
                            [extension] => php
                            [kind] => file
                        )

                )

        )

)

并返回文件的内容数组：

                            [index] => Array
                                (
                                    [path] => site/blog/index.php
                                    [name] => index.php
                                    [extension] => php
                                    [kind] => file
                                )

如果您能帮忙，我们将不胜感激！

Answer 1

只需对数组进行索引：

$b[$a[1]]['content'][$a[2]]['content'][str_replace('.php', '', $a[3])]

如果您的输入可以是可变长度的，请在循环中执行此操作。

Answer 2

所以你需要..。

$array2[$array[1]][content][$array[2]][substr(0, stripos($array[3], "."), $array[3])]

或者接近的东西..。

Answer 3

$path = array('site', 'blog', 'index.php');
$node = array(...);  // the tree

for ($i = 0; $i < count($path) && !is_null($node); ++$i) {
  $p = $path[$i];
  $items = $i ? $node['content'] : $node;
  $n = null;
  foreach ($items as $it) {
    if ($it['name'] == $p) {
      $n = $node['content'][$p];
      break;
    }
  }
  $node = $n;
}
