Detailed Description

An infinite Iterator.

Author:

Marcus Boerger

Version:

1.1

Since:

PHP 5.1

This Iterator takes another Iterator and infinitvely iterates it by rewinding it when its end is reached.

Note:

Even an InfiniteIterator stops if its inner Iterator is empty.

 $it       = new ArrayIterator(array(1,2,3));
 $infinite = new InfiniteIterator($it);
 $limit    = new LimitIterator($infinite, 0, 5);
 foreach($limit as $val=>$key)
 {
 	echo "$val=>$key\n";
 }
