3. How do you get the values out of the C++ script?

Answer 1

1 . How do you pass the values from PHP to C++?

Ans: In php file, you could use exec function to execute your C++ binary file.
Example:

exec("/path/to/your/binary $var1 $var2", $output);

2 . How do you run the C++ script? Do you have to compile it first some how?

Ans: Of course, you can’t execute the C++ script directly, C++ is compiled language, you could just execute the binary file.

3 . How do you get the values out of the C++ script?

Ans: See 1, you will get the output form C++ by $output.
