Note Submitter: mcrosland@chello.nl If you need to replace the contents of a file, but are getting problems with ownership/permissions, ftruncate can be used to effectively delete the contents by truncating the size of the file to 0 thus; ftruncate($file,0); fwrite($file,$my_stuff); Using this method will allow you to replace the file contents without changing ownership. The alternative method of using unlink() to delete the file then replacing it with a new file is unsatisfactory because the file created will be owned by 'nobody'.
