cant execute python script from php

Question

here is my code in control.php:-

<?php
$output = shell_exec("/var/www/script.py");
?>

why i cant run the shell_exec() command when i run the php script..? it should call the script.py and execute the py script.. but, when i run the control.php script..

note that i tried to run a normal program by using php where i tried to open gedit by using the command below:-

 <?php exec('gedit');?>

the gedit is not executed..

anyone can help me?

Can you run "/var/www/script.py" in the BASH? if NOT, then check the script,make sure contain the following line:

#!/usr/bin/env python

then chmod +x script.py to make sure it is executable.

i can run the "/var/www/script.py" in the bash very well =) but not from the php itself..

have you disabled the selinux? the /var/www/script.py is usually a default folder for apache, you could run "getfacl" to check if the PHP interpreter has enough access to that script.

You probably need to specify python in shell_exec() explicitly:

$output = shell_exec("/usr/bin/python /var/www/script.py")

or

$output = shell_exec("python /var/www/script.py")

and you need to ensure that your script.py has a permission better than "-rwxrwxr-x" as your php probably is executed by a different user.

both cannot be run.. i may need a permission.. but how to get the permission and how to know which user is executing the php? i run the code using google chrome in linux..

@ShahAbdHafiz You type ls -ltr /var/www/script.py and then the first column you get is its permission

the reason is because of the php doesnt have the permission to write/read the py script in desktop.. so, just change the directory of the py to the same directory as the php file then eveything runs smoothly..
