PHP folder creation (mkdir) fail when using variable with slash in it

Question

I have application with cases ids structured with / in them, example: F-4/1, I am making upload script and making a folder for each case and it is failing on every /.

for F-4/1 it will make F-4 folder.

$prikaz8 ="F-4/1";

if (!file_exists('uploads/'.$prikaz8)) {
    mkdir('uploads/'.$prikaz8, 0777, true);
}

I tried escaping it but didn't work. I can not find any information on this and how to solve it, please advise.

When I make them manually, I have it mounted over sshfs it lets me create it. I know I can replace / with something else, but I would like to keep case number the same. Would I even be able to target such folder with PHP later after creation?

Odd.. What cmd did you run over ssh mkdir -p F-4/1? File names cannot/should not contain '/', whats ls -la uploads/ show, I pretty sure it wont be / (looks like thunar is showing nested folder if only one folder, but thats odd too) — Lawrence Cherone

@LawrenceCherone I used OS X, not Linux to create it, i have disk mounted with sshfs, not ssh but I seen now on Linux it gets translated to :, but on OS X its shown like /. Yeah i can not do that... — ikiK

if you store the filename in a db you can then call it what you like, store it with normalised filenames — Lawrence Cherone

@LawrenceCherone Yeah i will have to save info anyway. So I will just sanitize everything. The fact that OS X let me create it got my hopes up and confused me. I will have to adjust this based on servers, because this app will end up in-house on different servers. Thank you for your time. — ikiK
