[PHPTAL] PHPTAL_RepeatController and PDOStatement

[Iván -DrSlump- Montes]

As far as I know a PDOStatement object implements the Countable
interface for the number of columns not the rows. This means that the
repeat controller will give a 'wrong' value for the 'end' attribute in
the loop.

To solve it either you need to modify the RepeatController to detect
PDOStatement objects and fetch all the rows at instantiation time and
count them, or you manually preprocess the statement and convert it to
an array or an iterable object before using it.

Another option would be to rewrite the Repeat attribute to only work
with and Iterator object (using ArrayObject for arrays) and change the
logic it uses to detect the last item in the set by pre-fetching the
next item at the end of the loop and checking its validity.
