Renaming a User Selected File

[ShoeLace1291]

Ok, I have an upload script that allows users to upload images to the server/database.  My problem is that if a user uploads a file with the name of a file that already exists on the server, it overwrites the existing file.  If I have a script that randomly generates 3 letters/numbers, how would I insert those in between the file name and the file extension?  I'm thinking the solution would have something to do with implode, but I'm not sure how I would use it.

 

I'm using the $_FILES['upfile']['name'] variable.

 

Thanks for any help.

You can check if the file exists by using the file_exists function prior to uploading.

 

Never done this so I can't be 100% sure. With the move_uploaded_file function you can specify the path. For example:

 

move_uploaded_file($_FILES['upfile']['name'],<where you want it/filename>)

use http://www.php.net/manual/en/function.rename.php

 

then concat your randomize letter or number

if (file_exists(filename)){

rand() //etc...

rename('oldfile', $randomizedletterornumber.yourfilenametoupload)

}

Will something like $_FILES['upfile']$combo['name'] work?

try it and expect errors lol

 

i guess no it wont work

Well since $_FILES['upfile']['name'] displays for example name.gif, I need something that would only display "name" without the extension.  Is there any way to do that?

[teng84]

str_replace(".gif","","$_FILES['upfile']['name']");

 

but y?

Well the script needs to rename the file to say filenamea4u.gif if the name filename.gif already exists.  Kinda like what image shack does.

}

 

 

 

is this wrong?
