What’s wrong with my PHP curl request, please help .. I’m not getting any data back
I’m posting XML data to a URL that is supposed to send me (echo) back results, and instead of sending them back to me , this is what I get after running the PHP .. My curl code is below this result … I am suspecting that something might be wrong with my CURL code below, how can I actually get the results back from the XML data posted to the URL(mysgproc.php), I posted the url code as well ? Thanks a bunch

msgproc.php has dependencies. No one has the time to debug it. So do this:
Try tracing into the server processing code.
Poor man’s debugging. And see where output stops, slowly pinpoint the issue. Also set_error_handler and set_exception_handler and see if anything gets caught.
