Description:
------------
When a class is expecting an array as in the example, it's waiting for
$vars['var'], and a string is given, $vars['var'] still returns true.
It picks up the first character of the string. isset($vars['var'])
should return false if a string is passed.
Normal arrays given to the class work fine. if the key is there, it
returns true, if not then it returns false. But a string always returns
true and it picks up the first character.
Reproduce code:
---------------
URL = http://www.legaciesleft.net/php/temp/source.php
Script.php ----
<? include 'class.php';
echo "test 1: ";
$class_one = new problem(array('var'=>'good'));
echo "<BR>test 2: ";
$class_two = new problem(array('novar'=>'bad'));
echo "<BR>test 3: ";
$class_three = new problem('string');
?>
Class.php ----
<?
class problem{
function problem($vars) {
if (isset($vars['var'])) echo $vars['var'];
else echo 'array is not set';
}
}
?>
Expected result:
----------------
test 1: good
test 2: array is not set
test 3: array is not set
Actual result:
--------------
test 1: good
test 2: array is not set
test 3: s
