Execution of a Python Script from PHP

Question

I am making an android application in which I am first uploading the image to the server and on the server side, I want to execute a Python script from PHP. But I am not getting any output. When I access the Python script from the command prompt and run python TestCode.py it runs successfully and gives the desired output. I'm running Python script from PHP using the following command:

$result = exec('/usr/bin/python /var/www/html/Source/TestCode.py');

echo $result

However, if I run a simple Python program from PHP it works.

PHP has the permissions to access and execute the file.

Is there something which I am missing here?

Answer 1

exec('/usr/bin/python /var/www/html/Source/TestCode.py', $output);

var_dump($output);

2nd Parameter of exec will give output

EDIT:

exec('/usr/bin/python /var/www/html/Source/TestCode.py 2>&1', $output);

2>&1 - redirecting stderr to stdout . Now in case of any error too, $output will be populated.

1. First Check your python PATH using "which python" command and check result is /usr/bin/python.

2. Check your "TestCode.py" if you have written #!/usr/bin/sh than replace it with #!/usr/bin/bash.

3. Than run these commands exec('/usr/bin/python /var/www/html/Source/TestCode.py', $result); echo $result
