Server Sent events not working on WAMP (1 reply)

I am trying to implement a server sent event in WAMP and somehow cannot make it work properly. php waits until the entire long script finishes before it sends back data all the while delaying all the progress data I am supposedly sending back. Instead it sends them all together at the end which makes it useless.

However, if I upload the same code to my webhost, it worked flawlessly. it sent at regular intervals as expected.


Is there any setting that I need to turn on to make this work with WAMP?

Thank you very much
