exec（）和system（）命令不起作用（php）

Question

I am using wamp 2.2e. I have tested the PHP on tha server and it works.

Now, I have a script called scriptA.py that I want to execute. I am not using safe mode, and in the php.ini the disable_functions line is empty. Ok, so I tried:

 exec("C:\wamp\www\scriptA.py")
 exec('C:\wamp\www\scriptA.py')
 exec('C:\\wamp\\www\\scriptA.py')

same with system()... tried with "cmd /c"..

none worked.

I also found a potential reason - maybe I need to set permmisions to the cmd using the CALC command, but I dont know what is my user, is it the computer name in control panel->system ?

please assist me

OK, there is a progress, now the browser shows me the errors:

Warning: exec() [<a href='function.exec'>function.exec</a>]: Unable to fork [C:\wamp\www\Telnetshutdown.py] in C:\wamp\www\index2.php on line 2
# Time Memory Function Location 
1 0.0005 362784 {main}( ) ..\index2.php:0 
2 0.0005 362912 exec ( ) ..\index2.php:2 

( similar if i try with system() ) - does it help ?

You probably have to invoke these via the Python executable as it's unlikely Python.exe is in the PATH of your apache user:

exec('C:\Python3\Python.exe C:\wamp\www\ScriptA.py');

There are several gripes with exec on Windows. You may find that refactoring your Python code to PHP is far less time consuming and more secure than giving apache user access to the whole disk like this.
