Running a Python Script from PHP

Running a Python script from PHP

Tested on Ubuntu Server 10.04. I hope it helps you also on Arch Linux.

In PHP use shell_exec function:

Execute command via shell and return the complete output as a string.

It returns the output from the executed command or NULL if an error
occurred or the command produces no output.


$command = escapeshellcmd('/usr/custom/');
$output = shell_exec($command);
echo $output;


Into Python file, verify this text in first line: (see shebang explain):

#!/usr/bin/env python

If you have several versions of Python installed, /usr/bin/env will
ensure the interpreter used is the first one on your environment's
$PATH. The alternative would be to hardcode something like
#!/usr/bin/python; that's ok, but less flexible.

In Unix, an executable file that's meant to be interpreted can indicate
what interpreter to use by having a #! at the start of the first line,
followed by the interpreter (and any flags it may need).

If you're talking about other platforms, of course, this rule does not
apply (but that "shebang line" does no harm, and will help if you ever
copy that script to a platform with a Unix base, such as Linux,
Mac, etc).

This applies when you run it in Unix by making it executable
(chmod +x and then running it directly: ./,
rather than just python

To make executable a file on unix-type platforms:

chmod +x

Also Python file must have correct privileges (execution for user www-data / apache if PHP script runs in browser or curl)
and/or must be "executable". Also all commands into .py file must have correct privileges.

Taken from php manual:

Just a quick reminder for those trying to use shell_exec on a
unix-type platform and can't seem to get it to work. PHP executes as
the web user on the system (generally www for Apache), so you need to
make sure that the web user has rights to whatever files or
directories that you are trying to use in the shell_exec command.
Other wise, it won't appear to be doing anything.

How to execute python script from php?

You can make an :


$command = escapeshellcmd('/usr/custom/');

echo $output;

Can't execute python script from PHP (apache2)

In case anyone has the same problem in the future, here's what I found out.

By executing some different commands via shell_exec, I noticed that it was behaving differently than my terminal.

enter image description here

So I find out that when I execute python3 over shell_exec, it was not pointing to the right address, then all I had to do was to pass the right address:

$result = shell_exec("/Library/Frameworks/Python.framework/Versions/3.7/bin/python '$name' ‘$email’ ”);

And now the script works :)
