New Comment:
Well, you may have tagged it bogus, but it's no use to have a
"Warning", when the behaviour should be different. The pattern is not
matched so regardless of the (type and value of the) replacement, the
replacement should not take place. So I still think this is a bug.

Try increasing your error_reporting level:
Warning: preg_replace(): Parameter mismatch, pattern is a string while
replacement in an array.

Description:
------------
When upgrading to 4.3.2 this started to happen:
whenever I use
$string = preg_replace("/\[$pattern\]/",$replacement,$string)
and the $pattern is empty or does not exist, but the replacement is an
array, my string is made empty.

Reproduce code:
---------------
$data = array(
"field1" => "somevalue",
"field2" => array("hmm","whassup"),
);
$html = '<b>[field1]</b>
,<h1>[field3]</h1>';
while (list($field,$fielddata) = each ($data)) {
$html = preg_replace("/\[$field\]/",$fielddata,$html);
}
print $html;
# will print nothing. however if you comment out the line "field2" etc
above, it will print something
Expected result:
----------------
output should be :
<b>somevalue</b>
, <h1>[field3]</h1>
Actual result:
--------------
no output, the string $html is empty
