My unoconv works perfectly in terminal using www-data, but no pdf file when executed through php

[simkimsia]

I am using nginx as my web server.

My OS is ubuntu 12.10 running in virtualbox as a guest OS.

When I ssh into my ubuntu 12.10 guest OS, I can execute unconv perfectly.

When I run as a php script it fails.

Weirdly, when I run php -r "exec(...);" in terminal, it works as well.

I have tried being explicit about the UNO_PATH. No use. I have tried all the troubleshooting by other people. My php script always returns a sucess signal about executing the unoconv, but there is no pdf file.

I also have no error messages whatsoever, so this is a bit frustrating.

I wrote the following function in php

public static function convert($originFilePath, $outputDirPath, $toFormat)
{
    $command = 'echo $PATH & UNO_PATH=/usr/lib/libreoffice unoconv --format %s --output %s %s';
    $command = sprintf($command, $toFormat, $outputDirPath, $originFilePath);
    exec($command, $output, $result_var);

    return compact('output', 'result_var', 'outputDirPath', 'originFilePath', 'toFormat');
}

This is my result after execution:

2013-05-26 03:05:30 Error: Array
(
    [output] => Array
        (
            [0] => /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
        )

    [result_var] => 1
    [outputDirPath] => /var/virtual/storyzer.com/cake-json/ltequotationapp/webroot/outputfiles/Excel/2
    [originFilePath] => /var/virtual/storyzer.com/cake-json/ltequotationapp/webroot/outputfiles/Excel/2/dsadas.xlsx
    [toFormat] => pdf
)

Please advise.
