    Hi,

    on my server, the pdf conversion with libreoffice didn't work.

    After inspection, the command

    passthru($libreOfficePath . ' --invisible --convert-to ' . $extension . ' ' . $docSource . ' --outdir ' . $outdir . $outputDebug, $codeReturn);

    returned an int(77) inside $codeReturn (ie. a "permission denied" unix code)

    The command

    passthru('whoami');

    correctly displays 'apache'

    Finally, I understood that on my server the user 'apache' has no home directory.

    My solution to make the convertor work correctly was to add the shell variable before : 

    passthru('export HOME=/tmp; ' . $libreOfficePath . ' --invisible --convert-to ' . $extension . ' ' . $docSource . ' --outdir ' . $outdir . $outputDebug);

    Hope that this solution will help.
