executing C++ prog with PHP????

svenjonas

How do I use exec() in php?
I've got a C++ program (taking one argument) that I want to execute and then display the result on a php page. HOW?

Hi,

reading the php manual

http://www.php.net/manual/en/function.exec.php

you can use exec. If you supply an array as second argument the array would contain every line of output and you can use the array to do whatever you want.

The first argument is the complete path to your c++ program. You might want to use escapeshellcmd to if you call the program with user provided arguments (e.g. by submitting a form) to prevent the users to submit arguments to your program that would render your OS unuseable.

I know this works fine for simple arguments. But if you'd had to pass a more complex argument, such as an array, nothing that I tried worked other than using the serialize() function and then coding a parsing function in C++ to rebuild such an array.

Hope you have a more straight forward and easier to use method.
