Updated by: jeroen
Reported By: sander <email protected>
Status: Open
Bug Type: Documentation problem
Operating System: Win2K & Debian Linux
PHP Version: 4.0.6
New Comment:
An uninitialized variable equals NULL. So it _is_ null.
This should be in the language.types.null section.

If it's intended, then it should be documented.
Reopened as a documentation problem.

Intented behaviour. Not a bug.

is_null() evaluates true for non-existent variables. Consider the following snippet:
unset($foo);
if(is_null($foo))
echo 'true';
else
echo 'false';
It outputs 'true'.
Can this be fixed before 4.0.7?
