Either the form munged part of my data (unlikely) or I pasted it in wrong. The
line after
if (!empty($_GET['search']['filter'])) echo 'SEARCH FILTER PARAM WAS PROVIDED!';
should be
$_GET = array('search'=>1);
if (!empty($_GET['search']['filter']))
echo 'SEARCH FILTER PARAM WAS NOT PROVIDED!';
I'd edit it, but it seems you can't: you can only add comments...

Description:
------------
Running on PHP Version 5.3.5, EasyPHP Server Apache.
The test code on my system shows "SEARCH FILTER PARAM WAS PROVIDED" if
?search=1
is passed for the query string but curiously not if ?search[a]=1 is provided.
Based on some other bug reports (#27677) I thought maybe the behavior was
correct,
but if so then it seems a bug that when _GET is manually set to the same value
instead of set by PHP parsing the query string, that it gives different
results.
So it seems a bug either way. :)
Test script:
---------------
<?php
# Assume http://somesite/?search=1
if (!empty($_GET['search']['filter'])) echo 'SEARCH FILTER PARAM WAS PROVIDED!';
# The REALLY odd thing is if I do this it does give the expected results:
$_GET
if (!empty($_GET['search']['filter']))
echo 'SEARCH FILTER PARAM WAS NOT PROVIDED!';
<?php
# The following (which obviously should be run as a separate script)
# demonstrates that the $_GET array seems the same in both cases
# It seems like empty() is somehow seeing the _GET array as set by PHP
# and the manually set _GET array as different when containing identical
# contents!
# It seems very odd to me!
var_dump($_GET);
if (!empty($_GET['search']['filter']))
echo 'SEARCH FILTER PARAM WAS NOT PROVIDED!';
$_GET = array('search'=>1);
var_dump($_GET);
if (!empty($_GET['search']['filter']))
echo 'SEARCH FILTER PARAM WAS NOT PROVIDED!';
Expected result:
----------------
SEARCH FILTER PARAM WAS PROVIDED if ?search[filter]=1 provided
No "SEARCH FILTER PARAM WAS PROVIDED" if ?search=1
Actual result:
--------------
SEARCH FILTER PARAM WAS PROVIDED if ?search=1 or ?search[filter]=1 provided
