Topic: How to make Apache to allow an executable to leave a file?

[thejustpark]

Hey guys,

I am just wondering what I can do in this situation.
I have this simple web page, through which I want to invoke a program that leaves a file on site.
For your information, this web page itself can write (it saves uploaded files in a specific location in the server).
But the problem is that when I invoke the program via the web page (using a native system call in php), it doesn't produce a file in the same specific location the web page succeeded to leave a file.

Simply speaking, my situation is
a web page can save a file to folder A,
but when the web page invokes a program to leave a file in the folder, it can't.
And the question is
how I can make the program to do so when it's invoked by the web page?

Thanks,
HJ.

Error log?

I guess that is has to do with the persmission of that folder. Which OS do you run?

Yes I realized that error messages do not come.
And on the Internet I found why based on the first reply on http://php.net/manual/en/function.system.php.

And the error log talked about the permission, so I changed the permission to 777, and now it's working.
Anyway, thanks a lot!
