I've created a file via

$my_dir = '/var/example'

$file_path = tempnam( $my_dir, '' );

Then I tried to convert temp file ($file_path) to dir.

There is no function tempdir.

How can I create dir with unique file name inside $my_dir? Even, if $my_dir contains a lot of sub dirs.

Dir name needs to be unique and not necessarily to be random.

Suggested question and answer - is not an answer for my question.

Suggested answer possible could conflict if there is subdir with generated name by uniqid function. I need to guarantee - there are no conflicts with existing subdir inside $mydir.

I need to solve the problem similarly how tempname works. Analogically, but for directories.

Acording to @RiggsFolly I've found this solution

$file_path = tempnam( $books_dir, '' );
unlink($file_path);
mkdir($file_path);

But theoretically there could be conflict and mkdir then could return false, If I start this script multiple times in parallel mode.

Good solution, but not ideal.

Do you want to create a Temporary Directory, or a permanent one – RiggsFolly Jul 06 '20 at 11:09
Permanent with a random unique name – 123 Jul 06 '20 at 11:10
@RiggsFolly, its not the answer for my question. – 123 Jul 06 '20 at 11:20
But it gives you all the pieces you need to write code to do what you want – RiggsFolly Jul 06 '20 at 11:23
It gives me nothing with my problem – 123 Jul 06 '20 at 11:28

`unlink($file_path); mkdir($file_path);` However this will create a directory like `abcd.tmp` so you may want to remove the `.tmp` extension – RiggsFolly Jul 06 '20 at 11:34
