This issue is related to following issue: Search multidimensional array in PHP and return keys

我有以下阵列我想搜索的字符串使用例如常规的前pressions

I have following array I would like to search for strings using e.g. regular expressions:

[390] => Array
(
    [0] => hammer
    [1] => Properties
    [2] => tools, hammer, properties
    [3] => 
    [4] => done
    [png] => Array
        (
            [0] => hammer_16x.png
            [1] => hammer_32x.png
        )

    [eps] => Array
        (
            [0] => hammer_16x.eps
            [1] => hammer_32x.eps
        )

    [ico] => Array
        (
            [0] => hammer.ico
        )

)

我想特别是搜索这些值：

I would like to especially search these values:

 [0] => hammer
 [1] => Properties
 [2] => tools, hammer, properties
 [3] => 
 [4] => done

例如。为火腿进行搜索时，用户必须要找到这个数组键的可能性，工具，AMM等。

e.g. the user shall have the possibility to find this array key when searching for "ham", "tools", "amm" etc.

我试着去适应张贴在上面后的解决方案，但并没有对其进行管理。我还发现一个解决方案使用array_map，但这并没有使我在一个特定的属性明确搜索（例如：我想进一步对限制搜索数组中的第一个索引，这里[0] =>锤）

I tried to adapt the solution posted in the post above but did not manage it. I've also found a solution using array_map, but this did not enable me to explicitly search in a specific attribute (e.g. I would like to further on limit a search to the first index in the array, here [0] => hammer):

$result= array_map('unserialize', preg_filter('/'.$searchterm.'/', '$0', array_map('serialize', $array)));

您的想法是欢迎的。
谢谢！

Your ideas are welcome :) Thanks!

推荐答案

您可以使用的 preg_grep ：

function preg_grep_recursive( $pattern, $input, $flags = 0, &$output = array() )
{
    foreach($input as $key => $val) {
        if(is_array($val)) {
            preg_grep_recursive($pattern, $val, $flags, $output);   
        } else {
            $output[] = $val;
        }
    }

    return preg_grep($pattern, $output, $flags);
}
