Running the example of documentation on the site works.

Examples:

echo exec('whoami');

$output = shell_exec('ls -l');
echo "<pre>$output</pre>";

My code does not differ so much from the examples described in the documentation, what I want to do is just run another application with the following command:

My code/example:

> $comando = "python3 caminho/arquivo.py";
> exec($comando);

And now folks!?

php linux shell-script exec

  • Do you want to run a Python or PHP file? Or do you have a PHP application that runs a Python file?

  • Yes, I have an application running in PHP that will run a python file. To be more exact the application will give the command execution in the terminal to run a python script. Which in my case the command is: python3 path/file.py

  • What’s the problem? I couldn’t understand it very well. What would be "not working properly?". If there is an error message or some unexpected behavior, edit your question and add more information

  • does not work correctly refers to the point of which for commands like: ls, mkdir, pwd. It works, but "python3 path/file.py" is a command just like any other and it doesn’t run/work.

  • check the permission in the directory and in the file you want php to run
