stripping multiple extensions off filename

Postby quiknot » Thu Apr 24, 2003 11:42 am

Hi, I need to be able to take a filename, say test.tar.gz and rename it to test.tgz. So I would like to be able to strip off the extension(s), check to see if they are .tar.gz, and if they are, create the file test.tgz. Anyone got some code to do this? Tried using the examples under basename at but could not find the right one.

$renamed_file = (substr($file,-7) == '.tar.gz') ? rename($file,substr($file,0,-7).'.tgz') : NULL;

check the numerics on that though.
