Description:
------------
Using MySQL and InnoDB table, if you prepare this query:
SELECT * FROM foo WHERE id IN(:values);

You will be totally unable to use it, thoses solutions doesn't work:
$arr = array(1,2,3,4,5);
$prep->bindParam(':values',	$arr, PDO::PARAM_STMT); //Invalid Array to String conversion

or:
$arr = array(1,2,3,4,5);
$prep->bindParam(':values',	implode(',', $arr), PDO::PARAM_STR); //Seems to be interpreted as "1,2,3,4,5" instead of "1","2","3","4","5" or plain integer values.

============

Actual work arround is to generate a string to inject in the query string before preparing it. But it's not a good solution as I often need to use prepared statement in loop. So if I must prepare and reprepare and re-reprepare, that's not usefull.

============

A PDO::PARAM_RAWSTR or PDO::PARAM_UNPROTECTED_STR might be a quick & good workarround to solve this problem until a better fix.


Reproduce code:
---------------
$arr = array(1,2,3,4,5);
$prep->prepare('SELECT * FROM foo WHERE id IN(:values);');
$prep->bindParam(':values', implode(',', $arr), PDO::PARAM_STMT);
$prep->execute();

Expected result:
----------------
SELECT * FROM foo WHERE id IN(1,2,3,4,5);

Actual result:
--------------
SELECT * FROM foo WHERE id IN("1,2,3,4,5");
