Answer 1

Did you try to look up shell_exec http://php.net/manual/en/function.shell-exec.php and PHP shell_exec() vs exec() ?

In addition i cant see your dir structure but php will probably require you to declare where from you execute your scripts. http://php.net/manual/en/function.dir.php

Answer 2

You need to pass variables like below

$prog = 'pathtopythonfile/filename.py '.$variable1.' '.$variable2;
shell_exec($prog);

inside python file, u can get variables like below

import sys

var1 = sys.argv[1]
var2 = sys.argv[2]

Answer 3

I cant add comments at the moment so you could see this as a comment: What output do you get or do you get any errors? You're asking for help but not saying what's wrong.

Also there is a system function in php for this case: http://php.net/manual/en/function.system.php

$output = system("python3 caller.py ".$time, $executioncode);
