php exec fails when python imports a file

Question

I have this code in php:

$var = "something";
$result = exec("python /somePath/someFile.py $var");
print $result;

and my someFile.py is like this:

import functions as f

x = f.removeSpace("hey   there")
print x

Now, without the import functions everything is ok, but when I try to import another module then php screws. I have included sys.stderr = sys.stdout in my python file, and when I run my php code then it returns:

AttributeError: 'module' object has no attribute 'removeSpace'

Any suggestions?

I had a problem like this recently. It turned out that PHP's exec wasn't passing environment variables through to the program it executed, so Python wasn't seeing $PYTHONPATH, and didn't know where to import the module from.

I don't know how to fix that from PHP, but in our case, symlinking the imported package to the same directory as the script made it work.

Check your functions module, see if you have defined an removeSpace function.

It's not a PHP issue, it's Python issue, you may have forgotten to define that function.

You said: Now, without the import functions everything is ok, but when I try to import another module then php screws. not when I execute it normally as you said in this comment!

I don't really know about python, but I think the problem is someFile.py can't find your functions-module. Because you are executing it from PHP, it's pwd will be set to php's pwd, not /somePath/.
