I've used Spreadsheet_Excel_Writer
in PHP, and it's good enough. Not WYSIWYG, but it does generate XSL files, and I'm happy with it. Afterwards, you can use OpenOffice macro to convert the document to PDF. It works from command line, ergo, it works from PHP scripts too.
Or here's an even better way.
Use OpenOffice to write a Smarty template. Smarty is a cool templating engine for PHP, I recommend it for this purpose. Then generate pure HTML using PHP with Smarty. Finally, just convert the generated HTML into PDF using aforementioned method.
Reporting Revolutionized (tm).

Modded down? Ah, nevermind.
Anyways, this method works on a headless server without running X11. I've taken the script from the mentioned link (except I put it in preexisting collection "Standard" instead of "DannysLibrary") and then I've ran this command from Windows machine using PuTTY, and X was shut down on remote machine, and DISPLAY variable was not set, and ... well, in any case, there's no way OOo could find X11 to connect to.
$ openoffice.org -invisible -headless "macro:///Standard.Conversion.ConvertWordToPDF(`pwd`/logaritamska.doc)"
This works and I'm sure this would work great for anyone who'd need conversion from another format into PDF, including production of printable reports from HTML. By editing the macro you could, perhaps, even get OOo to read directly from stdin or from your temporary service URL, and output into predefined file. The script on the link is quite simple once you have the elementary code to expand.
Summary:
- generate reports as XLS or HTML
- convert them
- even though it's OOo, it works on headless machines
EDIT Jun 9 2009
I've tried to implement an online converter this way. You should make PHP run under the same user under which you created macros. This user apparently cannot be www-data. I've tried to use suphp, but for some reason it didn't change the user properly (posix_getuid()
kept returning 33 which is www-data). I'll edit this once I fix this.
EDIT Jun 26 2009
Guess it took me a while to report back. Yes, this works with suphp. I'm however not in position to show it live, since the only server I have runs a relatively critical web app which didn't have professional security auditing. This means one of the things we depend on to protect the backend is that the user under which frontend runs is a very very unprivileged user (such as www-data). Don't ask :-)
Hope this helps someone: yes, converting into PDF with OO.o is quite realistic. There's even some remote calling support in OO.o but I didn't study that just for purposes of writing this.
