You can use header() calls to redirect, but it is incompatible with
echo(). You can't send ANY output to the browser before a header() call.

But if you're redirecting, any output you send would not be displayed
anyway - so why bother sending it?

er... the requirement from my 3rd party provider is that i have to
reply -1 once receive the parameters from them.. so i put echo -1. is
there any other way to send instead of echo? the redirecting part is
something i wan to add on... it's not in the API they provided...


OK, you have to respond with a -1. But once you send ANY output, you can't use a header() call.

header() must be called before the headers are sent to the browser. And any output - even white space - will cause the headers to be sent. So you can either send a response or do the redirect. But the HTTP protocol (not PHP) won't let you do both.
