删除嵌套的foreach PHP中的嵌套数组

function removeNestedArray($array) {
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $array[$key] = removeNestedArray($value);
        }
    }
    return $array;
}

// 示例用法
$nestedArray = array(
    'key1' => 'value1',
    'key2' => array(
        'nestedKey1' => 'nestedValue1',
        'nestedKey2' => array(
            'nestedNestedKey1' => 'nestedNestedValue1',
            'nestedNestedKey2' => 'nestedNestedValue2'
        )
    ),
    'key3' => 'value3'
);

$modifiedArray = removeNestedArray($nestedArray);
print_r($modifiedArray);
