phamquocbuu / callbacks.php
Created September 21, 2013 01:39

/* Author: Keyvan Minoukadeh
This script demonstrates how you can set callback functions
to receive the HTTP response as it comes through.
The advantage of this is that you don't have to wait for the whole response
to be returned before you start work on it, you can monitor for certain headers,
start outputting while you're receiving, etc..
I wasn't aware these cURL options were available in PHP,
but noticed them being used by Alan Knowles:
