Question

I have a c++ program that I call with the following line:

 ./myProgram

However, I’d like to send some external variables to the program (this will eventually be called from PHP via the exec() method). I’ve searched and read that I should use arguments in the following way:

 ./myProgram <arguments>

However I’m not exactly sure how to use that. Do I separate the arguments by comma if I have more than one, do I need to put type before? And in the C++ file, how do I get these variables?

Can somebody point me to a tutorial for that? Or any other info, code example?
Thanks!

Answer 1

The command line args to your executable should just be seperated by spaces.

<?php
    echo exec('myProgram arg1 arg2 arg3');
?>

If your arguments are numbers etc… then you convert them to a string and pass that string to the exec command. C/C++ only accept string arguments in their main functions.
