1:1 call PHP from Python

Question

We're using Splunk (A tool to analyse machine data like log files) and have an application in PHP. For some data we need to do a call to our application in php (CLI-based). Unfortunately Splunk only supports Python calls.
Is there an easy way to 1:1 "forward/call" php with the same arguments and return the output, like a "passthru". I've found only parts of the solution with the socalled subprocess module but my python experience is zero, so can't get it to work.

For example, splunk calls:
python external_lookup.py argument1 argument2 argument3
- Then the python script should call (with the CLI arguments given to python):
php external_lookup.php argument1 argument2 argument3
- Then php writes its output
- Python captures that output and outputs it itself

Any help much appreciated, or a working example script even better.

Thanks in advance,
Vince

Using subprocess.call:

import sys, subprocess
sys.exit(subprocess.call(['php', sys.argv[0].replace('.py', '.php')] + sys.argv[1:]))

Edit: Made Python script return the value the PHP script returned.
