Renaming a User Selected File

Recommended Posts

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>)
