to loop through object keys and reset to the start, try this:

<?php



$obj = new stdClass();

$obj->Mon = "Monday";

$obj->Tue = "Tuesday";

$obj->Wed = "Wednesday";

$obj->Thu = "Thursday";

$obj->Fri = "Friday";

$obj->Sat = "Saturday";

$obj->Sun = "Sunday";



$infinate = new InfiniteIterator(new ArrayIterator($obj));

foreach ( new LimitIterator($infinate, 0, 14) as $value ) {

    print($value . PHP_EOL);

}



?>



will output:



Monday

Tuesday

Wednesday

Thursday

Friday

Saturday

Sunday

Monday

Tuesday

Wednesday

Thursday

Friday

Saturday

Sunday



Can be useful when doing date operations or recurring events
