Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

PDO does not implement query parsing it is entirely up to the 
database. So the features you are talking about would only 
work if supported by the underlying database.

Description:
------------
PDO doesn't allow one to SELECT or DELETE groups of records
based on their primary key.

Specifically, the SQL clauses WHERE ... IN (...) and WHERE ... = ANY
(...) does not work for more than one record.

As a workaround I can construct an SQL query and execute it myself but
that defeats the niceness of PDO.

Reproduce code:
---------------
the following should return the records with ID 1 & 2:

$dbh = new PDO('mysql:host=localhost;dbname=mobop', "root", "");
$stmt = $dbh->prepare("SELECT * FROM news_item WHERE news_item_id
IN(?)");
if ( $stmt->execute(array("1, 2")) )
        while ( ($row = $stmt->fetch()) )
                print_r($row);

But it doesn't.

The following execute statement fails as well:

$stmt->execute(array(array(2,1)))

NB: The intention of the 2nd example is that when binding an array, it
seems natural that PDO would assume its part of an IN or =ANY clause
and convert it into a bunch of comma separated keys automagically. Some
of the higher level PDO based O/R abstractions currently bouncing around
like Doctrine would then be able to support (without any modificaiton)
queries that affect multiple records.

Expected result:
----------------
Two records should be loaded.

Actual result:
--------------
One record is loaded.
