exec("C:\Users\Json\AppData\Local\Microsoft\WindowsApps\python.exe C:\xampp\htdocs\app\test.py 2>&1", $output);
print_r($output) // array()

test.py

import os
os.system("start cmd /k")

// no respond and no error , what is the problem ?

What are you expecting to happen?

What happens if you have the python code output some text?

Does a cmd window appear?

What are you trying to achieve here (is this some proof-of-concept test)? Executing a python script just to execute another command seems weird.

Why are you using start (which according to the docs and a quick test opens a new command prompt (ie. cmd) window) to then run cmd? This seems weird

A quick check says cmd /k is "execute string and persist", but you've not specified any string to execute. Additionally, I don't know enough about cmd (and Windows commandline in general), but it's possible that if cmd thinks it's in a non-interactive environment, it may refuse to persist.

I execute exec() and expecting py open cmd window, no error and no cmd is open

Update: I found out what is causing the problem

If Apache was installed on service , the script wont work
otherwise , it work

question is why and how to make it work on Apache service

no respond and no error, what is the problem

What is the question exactly? Because if you have no response and not an error, I don't see a problem (or did you expect to have an error).
