Yahoo! Pipes is an interactive feed aggregator and manipulation tool. It can combine, filter and sort multiple feed data and spit out a single customized feed that you can use for yourself or share with others.
Before today, JSON has been the only way for you to obtain the output data of a Pipe. Now, Yahoo! has provided a second way to do this: serialized PHP.
I’m sure those who are more proficient with PHP will find this feature very useful. Thanks Yahoo!
