Re: PHP-memory leak with COM-objects?

["Gustav Wiberg" <gustav@xxxxxx>]

Hi again!

I noticed I didn't pay enough attention to your question... Sorry for that.

The file is stored on the server!

And with COM-objects I managed to do a PHP-script - create a 
(Word)-COM-object to open a certain file (say c:\test.doc on the server). I 
changed te c:\test.doc from within the php-application and pushed Saved (in 
the Word-object that open up). And Yes, the content changed in the file 
c:\test.doc which is on the server.

TinyMCE or whatsoever is out of question. It must be word. I don't want to 
change a whole organisations policy about using word... :-)

Best regards
/Gustav Wiberg
