Is there a way to send data from a C++ program to a php script on a server? I'm basically trying to create an update server for this program, and I need a way to see if the program needs to be updated.

Yea, there is. It's called a file.

If you tell us what you're trying to do exactly, maybe some code.. we can help you out. Otherwise, i don't know how to help you.

I need it so that the user clicks an 'update' button in the program, and the program passes the current version to the update server for comparison.

Uh... wow.. you need to be more specific as to how you want to pass that data, but there are many ways.. one of the more commonly used methods these days is to send the data in a file and have the receiving program read it (by executing it, or having it check for new file data every so many minutes like a normal service). I would recommend using XML for this.

Additionally use can use SOAP, RPC, XML-RPC, uses a PHP fron-end to receive data via a POST (probably HTTP) and invoke a command line utility and pass in the data through the command line from the PHP script... etc.

I don't really care how it gets there, I just need a way to pass the version string from my program to the server, so the server can compare the recieved string to the version string on the server.

open a socket, and send the info to the script, be sure to include the correct headers

Yea, dizzutch. Good post. Oh, and did i mention you're wrong?

If you open a socket and send the info via post, guess where the response is going to go? You guessed it! Right back at you. For that to work correctly, the user must have the information in a form and hit submit defeating the whole purpose of getting the information to them. Have the C++ program write the info you want to std::cout and use this code to get it.

[php]
function getCmdResults($cmd) {
$str = " ";

$pipe = popen($cmd, "r");
while(!feof($pipe))
$str .= fread($pipe, 1024);
pclose($pipe);

return substr($str, 1, strlen($str) - 1);
}
// Example (windows): echo getCmdResults("c:\\path\\to\\your\\exe.exe");
// or linux: echo getCmdResults("/home/username/executable");
[/php]
