Thank you for your bug report.
Although you supplied code to reproduce the problem, it is more
complicated and longer than necessary. Please supply a short, complete
and understandable piece of code to reproduce the problem. This is to
make sure the problem is with PHP and not with the example.

<?php
$db = new PDO('mysql:dbname=test;host=localhost', 'root', '');
$array2 = array('gb', 'us', 'nz', 'fr', 'de');
$array3 = array('fr'=>true, 'de'=>true);
$array = array_diff($array2, array_keys($array3));
reset($array);
$size = count($array);
$in = '?';
for($i = 1; $i < $size; ++$i) $in .= ', ?';
$stmt = $db->prepare('SELECT
name FROM table WHERE
language = ?
AND code IN('.$in.')');
$stmt->bindValue(1, 'en', PDO::PARAM_STR);

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.

Description:
------------
bindParam doesn't work with vars returned by current(), next()
Reproduce code:
---------------
<?php
$array = array_diff($array2, array_keys($array3));
reset($array);
$size = count($array);
$in = '?';
for($i = 1; $i < $size; ++$i) $in .= ', ?';
$stmt = $db->prepare('SELECT name FROM table WHERE
language = ?
AND code IN('.$in.')');
$stmt->bindValue(1, 'en', PDO::PARAM_STR, 2);
$i = 1;
$element = current($array);
do {
$stmt->bindParam(++$i, $element, PDO::PARAM_STR, 2);
} while(($element = next($array)) !== false);
Expected result:
----------------
SELECT name FROM table WHERE language = 'en' AND
code IN('us',
'gb', 'nz')
Actual result:
--------------
SELECT name FROM table WHERE language = 'en' AND
code IN('0',
'0', '0')
When i change
$stmt->bindParam(++$i, $element, PDO::PARAM_STR, 2);
to
$stmt->bindValue(++$i, $element, PDO::PARAM_STR, 2);
i get:
SELECT name FROM table WHERE language = 'en' AND
code IN('us',
'gb', 'nz')
