Question

This is really weird.
Whenever I call something like

if(empty($this->input->post("foo")){//blabla}

The whole PHP is “down” and I get a blank page from the website (even when I don’t pass through this empty(input) line).

I know this is not the right method and it is stupid, I change the code to

if(!$this->input->post("foo")){//blabla}

Better I guess ?

Seriously, how come the empty(input) breaks down the entire PHP page ? (I can’t get any echo “something”).

You cannot use empty with functions, and neither do you need to. empty is a special construct that only works on variables and triggers a fatal error otherwise. See The Definitive Guide To isset And empty.
