I've got the following code.

$this->transform = new Phpdocx\Transform\TransformDocAdvLibreOffice();
    try { 
      $dest = "/OriginSystems/cache/application/Updraft/administrator/" . $uniqueReferenceID . ".pdf";
      error_log("FileName: " . $proc->getFileName());
      error_log("Destination: $dest");
        array("debug" => true)
    } catch (Exception $e) {

The resulting PHP log looks like this.

[28-Jun-2016 11:27:09 Africa/Johannesburg] FileName: /OriginSystems/cache/application/Updraft/administrator/10305949.docx
[28-Jun-2016 11:27:09 Africa/Johannesburg] Destination: /OriginSystems/cache/application/Updraft/administrator/10305949.pdf

As you can see, in this case I'm simply attempting to transform an existing Docx document into a PDF document. Nothing terribly fancy.

I'm using CentOS 7 as the server operating system and I've installed LibreOffice via Yum. My Phpdocx config file has the following in it.

; libreoffice or openoffice
method = "libreoffice"

; libreoffice installation path, absolute path
path = "/usr/bin/soffice"

The file, soffice, exists and works. However, when I run the PHP script I get the following error:

As you can see, the rename() command is failing because the file indicated in the first parameter doesn't exist. This is correct. I've checked afterwards and it doesn't exist.  When I run the transform command that is being sent to passthru() in the terminal as root, everything works quite well. When I run the same command as any other user I get a permissions error.

/usr/bin/soffice: line 56: cd: /root: Permission denied

This means (I think) that the PDF file isn't getting created in the first place due to permissions and so that the rename function bombs. I can't figure out what the permissions problem is though. Both the target and destination directories are usable by the web server. The Docx file is generated by Phpdocx and it is writing to that folder fine. I've also changed the tmp folder to the folder that the wev server has permissions to access as well.  Am I missing something with the permissions?  I did a straight install of LibreOffice. No weirdness at all.
