Bug description: returning NULL from constructor does no MEAN
When we return NULL from the constructor, our intend is to tell caller that
NO OBJECT IS CREATED. But in PHP this case does not work.
Please check the following example;
<?php
class Test{
var $myVar;
function Test($val){
if (is_null($val))
return NULL;
else
$this->myVar = $val;
return $this;
}
}
$a = NULL;
$t = new Test($a);
if (is_object($t))
echo "Although it must be NULL, it says OBJECT";
?>
I am developing a very huge API using PHP and this does not permit us to
continue. I think, there should be a way of doing this in a language which
support OOP constructs.
Sincerely,
Ziya Karakaya
