来自php的exec python

Question

I'm trying to run a python script from php with

$res = '';
exec('./home/Desktop/Scripts/fetch_matches.py', $res);

My python file starts with #!/usr/bin/python and has exec rights. For now I only have a print in there but it's not working(var_dump($res) gets me an empty array). What's missing?

Also, if I'll have different methods in that script, how would I call them?

Answer 1

You need to get rid of the . before the path. If it's a normal Unix/Linux system, /home is in the root of the filesystem. . means the current directory, so unless you've recreated the /home filesystem in the directory from which you're running the PHP program, the path is incorrect. Also, unless your username is Desktop, you're missing a directory between /home/ and Desktop/ - it should be your username. The pwd command will never return a . before the present working directory.

For your second question, please refer to the docs on calling Python from the command line. You can execute arbitrary code from the command line, which could be something along the lines of

python -c "from fetch_matches import Fetcher; Fetcher()"
