Change file extenstion with upload class

[eluser]dorwin[/eluser]
Hello,

I see I can rename a just uploaded file with this class :

file_name Desired file name

If set CodeIgniter will rename the uploaded file to this name.

Note:The filename should not include a file extension.

But is it possible to change file extension, like .JPG in .jpg without use ftp class ?
Because sometimes servers bug if mypic.JPG is called by <img src='mypic.jpg' />

Thanks !

You can use rename() to rename the file once it's been uploaded: http://php.net/manual/en/function.rename.php

Too willing to use CodiIgniter, we come to forget base php

Code:

rename($image['full_path'], strtolower($image['full_path']));

Thanks
