PHP Bug Type: Unknown/Other Function
Bug description: When using isset to check a variable returning true for an
array key when str
Description:
------------
If a variable is set to a string and isset() is used to check an array key
for that variable it returns true.
Reproduce code:
---------------
$var="foo";
if(isset($var['ed']))
{
//why are we in this section if $var is a string?
if(is_array($var))
{
// This doesn't happen
echo "It's an array";
}
else
{
// And yet this returns "f"
echo $var['ed'];
}
}
Expected result:
----------------
I would expect isset to return false;
Actual result:
--------------
isset returns true, because a check for any associative array index for
the var will return the first character.
