Description: ------------ there is a bug in safe_mode this object doesnt send data to client when save mode is enabled it's due to using function tempnam in OLE/PPS/File.php this function does'nt work correcly in safe mode

I can verify that this package returns a 0 byte file when using it in safe mode.

Well, my host (swiftwill.com) figured this bug out. Turns out this is not a bug, but basically the restrictions of safe_mode in PHP. This package tries to create a file in /tmp/ and based on some safe_mode restrictions, this is where it fails. You can fix this by setting the temporary directory for the file using this function: $workbook->setTempDir($AbsoluteServerPathToTheTempDir); Make sure the directory is chmod 777 This worked for me.

safe_mode as the name implies restricts usage of several php functions. The functions in question regarding this problem are tempnam() and fopen() http://fi.php.net/manual/en/features.safe-mode.functions.php You can either use the solution Lukas provided or run without safe_mode.

The script calling SpreadSheet_Excel_Writer() needs to have the Safe_mode gid and/or uid, chmod 777 is not sufficient.
