code in PHP:
function xxx() {
for($i=$_COOKIE;$i<100;$i++)
echo "$i aaa";
}
when on breakpoint on 'for' line, request is:
context_get -i 57 -c 0 -d 0
response is:
<response command="context_get" transaction_id="57"><property name="i" type="uninitialized"></property><property name="_COOKIE" fullname="$_COOKIE" address="4629936" type="array" children="0" numchildren="0"></property></response>

So the problem is there's no 'fullname' attribute for 'i' property.
Thanks in advance.
