php exec() not running python script

python

import sys

id_input=sys.argv[1] 

print id_input

php

<?php


$out="";
exec("python teste.py a  ",$out);
print_r($out);

?>

output of php: array()

output in command line: a

Both files are in the same directory and i am using XAMPP in Vista OS to run them.

Try using the full path to python, not sure where that would be in Vista — rjdown

For most things, yes. PHP isn't aware of the environment variables, it's the same in Linux too — rjdown

Didn't know. I think this will be an important post for beginners in php-python. — João Pedro

As per comments... the problem was that you need to specify the full path to the python binary, because PHP is not aware of the environmental variables such as PATH
