Trying to pipe a Python script

[BigBear]

I have a python script that I would like to be able to run from a webpage.

I am trying to call the script in php and pipe the output to a file.

Then read the output file and display it on the web page.

code:

system('python script.py > output.txt');

does not seem to work.

The output file is owned by www-data and it is empty.

in what way does it not work? What's the return value of the execution?
