Running Python scripts from using PHP exec()
Question
I want to run a python script in a button press event of a php/html file. I tried following. Is this possible with PHP exec()? But following didn't work. What is wrong with my code?
HTML file
<html>
<head></head>
<body>
<H3>Run Python Script...</H3>
<form name="input" action="test2.php" method="get">
<input type="submit" value="Submit">
</form>
</body>
</html>
PHP exec()
<html>
<head></head>
<body>
<H3>Executing...</H3>
<?php exec("first.py"); ?>
<H3>Completed...</H3>
</body>
</html>

exec Executes a command as if on the command line, running first.py just via bash won't work. You have two options:
Option A
You can tell the python parser explicitly to run the file with:
exec('python first.py');
Option B
Make sure your python script's first line is the path to python:
#!/usr/bin/python
#Python code...
Then call exec('./first.py')
(If you chose this option, you'll need to make sure the script is executable)
Conclusion
I'd probably go with option A as it's simplest and gets the job done without fuss.
Hope this helps :) x

试试exec("/usr/bin/python path/to/first.py")

There can be several problems with even your python script.
First: Can you run this script from console? (Do you have a #!/path/to/env/python in the script's beginning)? If not, then either add it to your script or to the exec function (without #!)
You can also use passthru instead of exec, so you can display the raw output of the script.
