    The InfiniteIterator class

    (PHP 5 >= 5.1.0, PHP 7)

    소개

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

    클래스 개요

    InfiniteIterator extends IteratorIterator implements OuterIterator {
    /* 메소드 */
    public __construct ( Iterator $iterator )
    public void next ( void )
    /* 상속된 메소드 */
    public IteratorIterator::__construct ( Traversable $iterator )
    public mixed IteratorIterator::current ( void )
    public Traversable IteratorIterator::getInnerIterator ( void )
    public scalar IteratorIterator::key ( void )
    public void IteratorIterator::next ( void )
    public void IteratorIterator::rewind ( void )
    public bool IteratorIterator::valid ( void )
    }

    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
