Difference between NULL and null in PHP,
Is there a difference between
null in PHP? Sometimes they seem to be interchangeable and sometimes not.
edit: for some reason when I read the documentation linked to in the answer (before posting this question) I read it as “case sensitive” instead of “case insensitive” which was the whole reason I posted this question in the first place…
Null is case insensitive.
There is only one value of type null, and that is the case-insensitive keyword NULL.
