My attempt to execute a Python script from a PHP file is encountering issues when it comes to loading a local library. Surprisingly, the PHP successfully calls the Python script without the local libraries, and manually launching the Python script works flawlessly.
Below are the minimal files that (do not) work:
index.php
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
</head>
<body>
<?php
$command = escapeshellcmd("./getter.py");
$output = shell_exec($command);
echo "<p>$output</p>";
?>
</body>
</html>
getter.py
#!/usr/bin/env python2
import got
if __name__ == "__main__":
print "Python2 working"
The got library is causing the issue.
Manually executing ./getter.py leads to successful printing, but the webpage remains blank.
If I comment out import got, the message appears on the webpage as well.
Further details:
- Operating System: Ubuntu 18.04.1
- Web Server: Nginx 1.14.0
- PHP Version: 7.2
- Python Version: 2.7.15rc1
- I am new to web development and yet to explore debugging tools.
- No issues occur with non-local library imports like
osandcsv. - Tried using a simpler command to run the Python script -
$output = shell_exec("./getter.py"); - Attempted changing
#!/usr/bin/env python2to#!/usr/bin/python2. - Both PHP and Python confirm they are in the directory
/var/html/www/test.
