I've done some testing with this issue, and this is what I found out:
<?php
$array = array(
"Interno",
"id"
);
$step = count($array) - 1;
foreach (range(0, $step) as $number) {
echo '<p>'.$number.'</p>';
}
$datetime1 = new DateTime('2010-08-2');
$datetime2 = new DateTime('2009-07-30');
$interval = date_diff($datetime1,$datetime2);
?>
the warning only comes up when the date_diff function is used. If the
date_diff command line is commented out, it range call does not throw
a warning. So I guess this is more a php bug(?) than a Cake problem.
