在PHP中将单数组转换为多维数组？

function convertToMultiDimensionalArray($array) {
    $result = array();
    foreach ($array as $key => $value) {
        if (strpos($key, '.') !== false) {
            $keys = explode('.', $key);
            $currentArray = &$result;
            foreach ($keys as $nestedKey) {
                if (!isset($currentArray[$nestedKey])) {
                    $currentArray[$nestedKey] = array();
                }
                $currentArray = &$currentArray[$nestedKey];
            }
            $currentArray = $value;
        } else {
            $result[$key] = $value;
        }
    }
    return $result;
}

// 示例用法
$singleArray = array(
    'name' => 'John',
    'address.city' => 'New York',
    'address.country' => 'USA',
    'skills.programming' => 'PHP',
    'skills.framework' => 'Laravel'
);

$multiDimensionalArray = convertToMultiDimensionalArray($singleArray);
print_r($multiDimensionalArray);
