Python Imports doesnt give output in PHP

Question

PHP code

<?php 
echo shell_exec(' python /Users/rushikesh/Sites/hello2.py ');
>?

Python code

print('hello')

import numpy as np

print('hello2')

It outputs only hello, why does the code doesnt give any output after import statements.

I even tried finding error

echo shell_exec(' python /Users/rushikesh/Sites/hello2.py ');

But still am getting blank output after import statements

How can you tell which print('hello') is being echoed in php? — tshimkus

Earlier part is being echoed because i tried changed the print statements — rushikesh jachak

Please check if you are executing the file which you've shown above, also try changing the string from 'hello' to anything to check which line is not executing — weegee

I have tried, earlier code is being executed before the import statement — rushikesh jachak

putenv('PYTHONPATH=/Users/rushikesh/anaconda3/lib/python3.6/site-packages:');

$command = escapeshellcmd('/Users/rushikesh/anaconda3/bin/python /Users/rushikesh/Sites/hello2.py');


output = shell_exec($command);

echo $output;

According to that question, the PYTHONPATH environment variable might not be set when using this script on a server. So setting it might be required, making this the correct answer.

Use python -u to skip Python's output buffer, but that still doesn't quite help if Python's library path is incorrect (exit status 3221225477). This works:

PHP start.
<?php 
$cmd = 'c:/python36-32/python -u hello.py';
echo shell_exec($cmd);
?>
PHP end.

print("Hello!")
#import sys; print(sys.path)  # Can we even find numpy?
#help('modules')  # Slow, so use -u flag for Python.
import numpy
print("Imported numpy.")
