Description:
------------
Since upgrading to php:
PHP 4.3.3RC3 (cli) (built: Aug 16 2003 11:22:58)
Copyright (c) 1997-2003 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend
Technologies
it seems that many of my php programs which use !
is_null($var) have broken, however when I replace the
function is_null for a comparison: $var != NULL, it works.
Is this a bug? Or some new "feature"?
Many thanks
Reproduce code:
---------------
Fails:
function name ($setTo=NULL)
{
if (! is_null($setTo))
{
return "Not null";
}
return "null";
}
Works:
function name ($setTo=NULL)
{
if ($setTo != NULL)
{
return "Not null";
}
return "null";
}
Expected result:
----------------
return null when null and not null when not null
Actual result:
--------------
works only with comparison != and not with !is_null()
function
