Php file upload without any error prompt, but this file does not exist after file Upload

Php file upload without any error prompt, but the file does not have the file foreach ($ _ FILES ['imgs '] ['type'] as $ k => $ v ){
If ($ v = "image/gif") | ($ v = "image/jpeg ") | ($ v = "image/pjpeg ")))
{
If ($ _ FILES ["imgs"] ["error"] [$ k] = 0)
{
$ Fname = md5 ($ _ FILES ["imgs"] ["name"] [$ k]). '. '. pathinfo ($ _ FILES ["imgs"] ["name"] [$ k], PATHINFO_EXTENSION );
Move_uploaded_file ($ _ FILES ["imgs"] ["tmp_name"] [$ k], $ fname );
}
}
Else
{
Echo "Invalid file ";
}

}

No error message... The location of $ _ FILES ["imgs"] ["tmp_name"] is C: \ WINDOWS \ php2EF. tmp, but no file found in this location .... I used to upload files. it's strange that this is not the case. There is also the winxp system of the local website.

C: \ does WINDOWS have anonymous user access?
You 'd better specify upload_tmp_dir

I have specified whether D: \ php2EF. tmp is displayed.

How many Upload controls do you have?

How many Upload controls do you have?

One has tried multiple of them.
I use the multiple-choice method to obtain the object. the obtained object is move_uploaded_file. if it is not mentioned as an error, no file is uploaded.

In addition, I can upload only one 1 non-repeating file in the standard format .... I was wondering if there was a problem with apache and PHP configuration.

Is_uploaded_file is also false. I don't know why.
