Run remote php file and retrieve results

[datona]

I need some guidence on how to do the following:

client fills out a form (form.php) and hits SUBMIT.
form.php contacts a remote php script that takes the inputed variables and executes a command using system()
If the system() command is successfull, some sort of responce is sent back and SUCCESS is updated on the screen.

I hope I was able to give enough data for someone to guide me in the right direction

Check out exec() which returns the last line of output. If you need all the output, then check out passthru(). You'll have to parse the output from these two functions to determine if they were successful or not (meaning your remote php script must provide some sort of message you could use to determine if it did its job or not).

For a remote script, try using fopen with a URL. You can specify form variables in the URL, then read the generated page as if it were a regular file.

For anything moderately complex you might want to look into XML-RPC instead. It provides a standard interface for this kind of remote access, and takes care of a lot of the little details so you can concentrate on the actual code. However, it requires both sides of the communication to support it, which may not be possible if the remote site is not under your control.
