C ++显示输出到php

Question

I have a C++ console application that returns some kind of things, then, I need to show that in a browser. So I tried to write every console.write from C++ to a .txt file for future PHP reading, but no success because it doesn't write the errors!

Then I tried to use exec('program.exe', $output); at PHP but no success too.. :/

• Is there another way to do that?
• Or any function in C++ that writes to a .txt every single thing that shows up in the console?
• Or some function in another Programming Language that catches everything in the console?

Answer 1

There are three standard file handles known as stdin, stdout, stderr. Looks like you're only fetching stdout right now. Try to redirect stderr to stdout.

exec('program.exe 2>&1', $output);

(works not only on *nix but also win32).
