使用exec（）调用python脚本时出错

Question

I am trying to call a simple python script

#!/usr/local/python25/bin/python
print "hello world"

from the following php script

 <?php
    echo exec("/usr/local/python25/bin/python myfile.py");
    ?>

But nothing was happened. Please tell me what is wrong here? (I also checked other thread but I could not solve my problem)

Question Solved: I forgot to give the permission to access /usr/local/python25/bin/python. After I did this, the problem solved. Thank you so much for your help!

Answer 1

If you want to capture the subprocess' stdout, you should use passthru

Also you don't need the first line of that python script if you're calling the python interpreter directly.
