根据深度嵌套数组PHP的值过滤多维数组

function filterArray($array, $value) {
    $result = array();
    
    foreach ($array as $key => $item) {
        if (is_array($item)) {
            $filteredItem = filterArray($item, $value);
            
            if (!empty($filteredItem)) {
                $result[$key] = $filteredItem;
            }
        } else {
            if ($item == $value) {
                $result[$key] = $item;
            }
        }
    }
    
    return $result;
}

// 示例用法
$array = array(
    'a' => array(
        'b' => array(
            'c' => 'value1',
            'd' => 'value2'
        ),
        'e' => 'value3'
    ),
    'f' => 'value4'
);

$value = 'value2';
$result = filterArray($array, $value);

print_r($result);
