Running libreoffice from php exec()

I have installed libreoffice headless on a freebsd-server with apache in order to convert documents programmatically (e.g. odt->pdf). It works from the command line! But my goal is to be able to do it from php. This demands that the web-user (www) can run libreoffice. But it cannot.

When running libreoffice as my own user, I get:

%libreoffice --headless -convert-to pdf Litteraturundervisningogit.doc
javaPathHelper: not found #This should not be a problem, says people on the net.
convert /usr/home/bundsgaard.net/www/jeppe/foredrag/Litteraturundervisningogit.doc ->
 /usr/home/bundsgaard.net/www/jeppe/foredrag/Litteraturundervisningogit.pdf using writer_pdf_Export
%

If I try the same command as root, it does not work. The same is the problem with the www-user from php:

sp# libreoffice --headless -convert-to pdf Litteraturundervisningogit.doc
javaPathHelper: not found
sp#

The problem is that I do not get any information from libreoffice, thus I don't know why libreoffice does not want to run as other users than my own.

My question is: How do I give the www-user permission to run libreoffice via exec() in php?

It is working for me.

You can convert docx to HTML by using libreoffice, You need to give proper permission output directory

exec("export HOME='/var/www/html/wp/wp-content/uploads/' && /usr/bin/libreoffice --headless   --convert-to html --outdir '/var/www/html/wp/wp-content/uploads/' /var/www/html/wp/wp-content/uploads/demo.docx");

This works for me.

Make sure you have installed java RE, for example in ubuntu:

apt-get install default-jre

First, find the location of your libreoffice

$ which libreoffice
/usr/bin/libreoffice

Include the folder location in the PATH, and also set the HOME var by adding these lines:

putenv('PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin');
putenv('HOME=/tmp'); 
system("libreoffice .....

I'll recomend put config path first you run exec() or shell_exec();

IE:

// Vars
putenv('PATH=/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin');
putenv('HOME=' . $outputdir);

$outputdir = chmod 777 And the same forlder from libreoffice command "--outdir"

About Universal Network Objects (UNO), there are some "plug-and-play" final-user tools, see Docvert and JODConverter (jODconverter and pyODconverter). All of then can be called as web-service or exec by PHP.

I managed to fix this issue with a quick export HOME=/tmp before running the convert command, this gives libreoffice somewhere writable to work it's magic.

I was having the same problem and yes (thanks Wrikken) after prepending /usr/local/sbin to the PATH environment variable I was able to run libreoffice as www-data under apache.

Not strictly an answer, but rather than using PHP's exec, you might consider using PUNO, a PHP5 module that provides access to the OpenOffice.org UNO Programming API.
