    The InfiniteIterator class

    (PHP 5 >= 5.1.0, PHP 7, PHP 8)

    Introduction

    The InfiniteIterator allows one to infinitely iterate over an iterator without having to manually rewind the iterator upon reaching its end.

    Class synopsis

    class InfiniteIterator extends IteratorIterator {
    /* Methods */
    public function __construct(Iterator $iterator)
    public function next(): void
    /* Inherited methods */
    public function IteratorIterator::current(): mixed
    public function IteratorIterator::getInnerIterator(): ?Iterator
    public function IteratorIterator::key(): mixed
    public function IteratorIterator::next(): void
    public function IteratorIterator::rewind(): void
    public function IteratorIterator::valid(): bool
    }

    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.
