'python' is not recognized as an internal or external command, operable program or batch file using PHP passthru()

Question

I am trying to invoke my python script from php by using passthru() function. I have already done that successfuly and for development I used xampp , now at some moment I installed manually apache,php and other add-ons. I also made changes to apache conf to make my python scripts work, some of them work when i invoke them directly via ajax,but scripts like this:

<?php

passthru("python C:/Apache24/htdocs/app1/pyscripts/export_zakup.py GARČIN
2>&1",$retval);
echo $retval;

?>

give me result like: 'python' is not recognized as an internal or external command, operable program or batch file. 1

Also when i copy python C:/Apache24/htdocs/app1/pyscripts/export_zakup.py GARČIN to my cmd it works properly. I have already spent few hours trying to find out where the problem is but unsuccessfuly. Anyone knows where the problem is?

It means there is no `pyton` global executable. Maybe add it to your PATH var or call directly — Justinas, Apr 03 '19 at 12:20
@Justinas how it isn't if I can call python from my cmd no matter in which folder I am positioned? — Goran, Apr 03 '19 at 12:22
Have you added python env variable in windows all user or current user ? — Googlian, Apr 03 '19 at 12:25

First, locate where the Python executable is by runniing which python from the command line:

$ which python
$ /usr/bin/python

Then use the full path to the executable in your PHP script:

passthru("/usr/bin/python C:/Apache24/htdocs/app1/pyscripts/export_zakup.py GARČIN
2>&1",$retval);
echo $retval;

Keep in mind that the path will be different on Windows vs. Linux based machines. For example the latest versions on Windows typically install the executable in C:\Python27\, so the full path would be C:\Python27\python
