首先，它必须验证图像计数最小02和最大05，然后文件大小最大8MB，之后仅允许图像类型"JPEG"和" PNG"，错误应为0。
然后我必须创建一个文件夹作为用户名(登录用户的用户名，它可以在会话中被请求(。 在该文件夹中，应创建另一个文件夹，如userName_ID_220(220为此，它必须从数据库中选择最后插入的id，可以使用数据库SQL max函数(。 在此文件夹中，图像应像userName_id_220_0.jpg一样移动和重命名，下一个图像应如下所示userName_id_220_1.jpg.
并且我必须将所有图像的路径保存在数据库中，例如 pic0 列中的用户名/userName_ID_001/userName_id_220_0.jpg，其他图像路径和名称应保存在 pic1 列中，如用户名/userName_ID_001/userName_id_220_1.jpg如下图所示。

我尝试了每个，但它为每个图像创建了每一行。 所以请给我一个解决方案。

我遇到了一些问题，例如如果我上传了 2 张图片，为 $file_type2 = ($_FILES['inputfcount3']['type'][2](出现错误未定义的偏移量; 如何修复该错误并简化此代码？
当您上传两张图片时，自然会给出此错误 - $file_type2是针对不存在的第三张图片。您必须将所有$file_type更改为：
$file_type2 = (isset($_FILES['inputfcount3']['type'][2]) ? $_FILES['inputfcount3']['type'][2] : '') ;
您的$_FILES数组如下所示：
Array
(
[inputfcount3] => Array
(
[name] => Array
(
[0] => test1.jpg
[1] => test2.png
)
[type] => Array
(
[0] => image/jpeg
[1] => image/png
)
[tmp_name] => Array
(
[0] => /tmp/phpq62nsC
[1] => /tmp/phpKTijeC
)
[error] => Array
(
[0] => 0
[1] => 0
)
[size] => Array
(
[0] => 63722
[1] => 3254
)
)
)
在我看来，您不需要任何foreach - 只需按照上面所示将数据库文件名放在一起即可。我有一个建议：使用basename($_FILES['file_upload_int']['name'])作为文件名。
基名称
这样，即使文件是png，您也不会覆盖以jgp结尾的文件。
出于安全原因，我还建议您使用PDO而不是mysql功能，并使用$_POST而不是$_REQUEST(以防您尚未按帖子发送表单(。
