This is another interesting problem that baffles the novice PHP programmers.
We make a quick change, and upload the file to webserver, we access the webapge and your are presented with a blank white page, aka ‘white screen of death’. It does not even show any error message.
We end up thinking what happened, we refresh the webpage but usually nothing changes.
Why this happens?
This happens because your host has switched off error reporting(for good reasons). So whenever their is a fatal error in your PHP script, and you have error reporting turned off you are presented with white screen of death.
