For php 5 3  you can use the SplFileInfo   class    spl   new SplFileInfo  filename    print r  spl- gt getExtension       gives extension    Also since you are checking extension for file uploads  I highly recommend using the mime type instead     For php 5 3  use the finfo class   finfo   new finfo FILEINFO MIME   print r  finfo- gt buffer file get contents  file name
