(move_uploaded_file) Can we have an incrementing extension?

[suttercain]

Good day!

 

I was wondering.... since I am currently learning about the (move_uploaded_file) function, I thought this would be the time to ask.

 

Let's say a user has permission to upload a file and they choose to do so.

 

User A decides to upload big_juggs1.jpg and the file is placed in sitename.com/images

Now user B decides to upload big_juggs1.jpg and the file is places in sitename/images

 

Normally the file would be overwritten... is there a way to attach and incremmenting number to the file name IF one already exists?

 

Example

 

User B's file would now become something like big_juggs1_0001.jpg

 

 

 

Thank you in advance for your time
