Problem in calling Python script from PHP
This is my python script which creates a "test.txt" file when executed. when I execute using terminal (Ubuntu 11.04) root@gml-VirtualBox:/var/www/HMS# python test.py . It creates the "test.txt" in the /var/www/HMS directory as I expected.
test.py:
#!/usr/bin/env python
def init():
filename = "test.txt"
file = open(filename, 'w')
file.write("This is the new content of test.txt :-)")
file.close()
print "done"
def main():
init()
if __name__ == '__main__':
main()
But when I try to call this test.py using PHP, It's not creating the 'test.txt' output file.
index.php:
$tmp = exec("python test.py");
echo "temp: $tmp";
Both test.py & index.php are in the same directory( /var/www/HMS/ ). But when I modified the test.py like this:
#!/usr/bin/env python
def init():
print "done"
def main():
init()
if __name__ == '__main__':
main()
It prints temp: done in the browser, which is what I expected.
I don't know why my previous python code didn't work as expected.
When you test the python script on the command line, you're running as root . Chances are you're not running the webserver as root (which is a good thing), and the webserver's user does not have appropriate permissions to create and/or write to that file.
