Rename file in PHP using rename() function

rename() function is nothing but an inbuilt function in PHP. This function can rename any file in PHP. But besides that, it can also be used to rename a directory.

rename(oldfilename, newfilename, context)

The very first two parameters are mandatory and the last one is optional here.

Parameters of rename() function in PHP

In this post, I will just show you how to rename a file in PHP. So I will use the first two compulsory parameters. That means the oldfilename and the newfilename.

  • oldfilename – this is the name of the file which you want to rename with a new name.
  • newfilename – this is your desired file name. That means the new name of the file.

If you set the newfilename to a file name which already exists in that directory than PHP will generate a warning. ( remember this is a warning, not an error, so the file will be overwritten in this case.
