Operating system: Slackare Linux Kernel 2.4.26
PHP version: 5.0.3
PHP Bug Type: Zend Engine 2 problem
Bug description: isset false positive
Description:
------------
isset() when run using mod_php returns a false positive when checking a
string variable for the presence of a property. isset() when run under the
cli behaves correctly and returns false. This is in PHP 5.0.3RC2.
Reproduce code:
---------------
<?php
$simpleString = "Bogus String Text";
if (isset($simpleString->nonExistentStringProperty)) {
echo "This line should not execute";
} else {
echo "This line should execute";
}
?>
Expected result:
----------------
This line should execute
Actual result:
--------------
This line should not execute
