Description:
------------
isset may return true to a $string->member being passed in. Clearly, a
string can not have a member variable; therefore, isset is expected to
always return false in this case. The actual result of the reproduced
code for us is incorrect when using php 5.0.3, while the expected
correct result is produced in php 5.0.0.
Reproduce code:
---------------
<?php
class Car
{
var $mpg;
}
$car = new Car();
$car->mpg = 30;
//the normal case, should work
if( isset($car->mpg) )
echo "mpg is set...this is normal<br>";
//the case that may not work right:
$some_random_string = "this is some random string, it has no mpg
member";
if( isset($some_random_string->mpg) )
echo "ERROR: This line should never be displayed<br>";
?>
Expected result:
----------------
mpg is set...this is normal
Actual result:
--------------
mpg is set...this is normal
ERROR: This line should never be displayed
