public void next ( void )

/* Méthodes héritées */

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

It is important to realise that rewind() must be called on any iterator before using it or you may experience undefined behaviour, see example code and output here http://3v4l.org/rvNpU



See this bug report https://bugs.php.net/bug.php?id=63823&edit=2 for a fuller explanation.
