PHP - Fileuploads, ['tmp_name'] doesn't exists physically

This is some very basic stuff. For a unknown reason i can't upload files via a standard HTML+PHP upload form.

The file doesn't exists locally under /tmp

php.ini

;;;;;;;;;;;;;;;;
; File Uploads ;
;;;;;;;;;;;;;;;;

; Whether to allow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
; http://php.net/upload-tmp-dir
upload_tmp_dir = /tmp/

; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 30M

; Maximum number of files that can be uploaded via a single request
max_file_uploads = 20

; open_basedir, if set, limits all file operations to the defined directory
; and below.  This directive makes most sense if used in a per-directory
; or per-virtualhost web server configuration file. This directive is
; *NOT* affected by whether Safe Mode is turned On or Off.
; http://php.net/open-basedir
open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/:/usr/share/webapps/

; Maximum size of POST data that PHP will accept.
; Its value may be 0 to disable the limit. It is ignored if POST data reading
; is disabled through enable_post_data_reading.
; http://php.net/post-max-size
post_max_size = 8M

upload code (resides in the same file as the html form, index.php)

print '<pre>';
print var_dump($_FILES);
print var_dump(is_uploaded_file($_FILES["file"]["tmp_name"]));
print is_writable('/tmp');
print '</pre>';

html

<form method="post" action="./" enctype="multipart/form-data">
    <label for="file">Filename:</label>
    <input type="file" name="file" id="file"><br>
    <input type="submit" name="submit" value="Submit">
</form>

And my output is:

array(1) {
  ["file"]=>
  array(5) {
    ["name"]=>
    string(11) "test.jpg"
    ["type"]=>
    string(10) "image/jpeg"
    ["tmp_name"]=>
    string(14) "/tmp/php66JkW8"
    ["error"]=>
    int(0)
    ["size"]=>
    int(75766)
  }
}
bool(true)
1

permissions and info about the file:

[torxed@archie http]$ ls -l / | grep tmp
drwxrwxrwt   9 root root   220 Sep 26 13:34 tmp

[torxed@archie http]$ ls -lh /home/torxed/ | grep test
-rw-r--r--  1 torxed users  74K Sep 26 13:08 test.jpg

Solved it myself. As silly as the question is, the answer was even sillier.

[torxed@archie http]$ ls -lh /srv/http | grep tmp
drwxr-xr-x 2 torxed root 4.0K Sep 26 14:10 tmp

I assumed that the file would live under /tmp long enough for me to witness it being created which was stupid in the first place.

But trying to use move_uploaded_file returned false when trying to move it into ./ Cause of this was wrong permissions for the folder.

move_uploaded_file($src, '/srv/http' + $src); by simply moving it to another temporary location worked (after fixing the write permissions on /srv/http/tmp)

Have you set post_max_size value to a higher one?
