I have a C++ program that needs to take data from a PHP script, process it, and return the data to my PHP script.

If you want to run a program written in C then you have to run the program and not the source code. Compile your C into an executable, then call the name of the executable from exec . Show activity on this post. You should compile your C program and then execute it with PHP.
Step 1: Open turbo C IDE(Integrated Development Environment), click on File and then click on New. Step 2: Write the C program code. Step 3: Click on Compile or press Alt + F9 to compile the code. Step 4: Click on Run or press Ctrl + F9 to run the code.
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.

1- you can use exec to call external application, use command line parameters
2- C++ is not scripting, its a compiled language, you have to compile it first
3- normal std out will be captured by php exec function
