#8047 — shell script with shell_exec()

I need to run some binaries from within php web pages.

Ironically, it's to convert Word/Excel to PDF, no joke, but open office 
does it pretty easily.  No need to buy someone's service.

My problem is, the cli version of PHP executes the scripts perfectly, but
the FreeBSD Apache module PHP 5.4.7 - which I believe doesn't have the 
safe mode, well it does a SIG_ABORT on the open office binary.

I've been reading web pages all day but don't see how to get around this.

You really didn't give us much to go on.  But my first check would be to 
ensure the web server user has sufficient permission to execute Open 
Office and it's libraries.  Also ensure it can read the file you're 
converting from and write access to the directory you're writing to.

Next thing I would check would be the log files for any messages.

Thanks for your help.  I figured it out, the www userid didn't have a 
tempdir/homedir, so setting HOME to /tmp solved it.

makes sense. In such cases having run with /tmp systems in the past that 
filled up, id be tempted to create something under /var/tmp


Unless the files are truly temporary and  vanish as fast as they are 
created..

diminishing number of producers.

For Excel to PDF I use phpExcel. It'll read an Excel file and write it
as a PDF.

For Word you might be able to do something with phpwordlib.
