The LimitIterator class

INTRODUCTION

	The LimitIterator class allows iteration over a limited subset of items in an Iterator.

CLASS SYNOPSIS

       LimitIterator

       LimitIteratorextends
       IteratorIteratorOuterIterator

       Methods

       o public LimitIterator::__construct (Iterator  $iterator, [int  $offset], [int  $count = -1])

       o public mixed LimitIterator::current (void  )

       o public Iterator LimitIterator::getInnerIterator (void	)

       o public int LimitIterator::getPosition (void  )

       o public mixed LimitIterator::key (void	)

       o public void LimitIterator::next (void	)

       o public void LimitIterator::rewind (void  )

       o public int LimitIterator::seek (int  $position)

       o public bool LimitIterator::valid (void  )

EXAMPLES

       Example #1

	      LimitIterator usage example

	      <?php

	      // Create an iterator to be limited
	      $fruits = new ArrayIterator(array(
		  'apple',
		  'banana',
		  'cherry',
		  'damson',
		  'elderberry'
	      ));

	      // Loop over first three fruits only
	      foreach (new LimitIterator($fruits, 0, 3) as $fruit) {
		  var_dump($fruit);
	      }

	      echo "
";

	      // Loop from third fruit until the end
	      // Note: offset starts from zero for apple
	      foreach (new LimitIterator($fruits, 2) as $fruit) {
		  var_dump($fruit);
	      }

	      ?>

	      The above example will output:

	      string(5) "apple"
	      string(6) "banana"
	      string(6) "cherry"

	      string(6) "cherry"
	      string(6) "damson"
	      string(10) "elderberry"

The ArrayIterator class

INTRODUCTION

	This iterator allows to unset and modify values and keys while iterating over Arrays and Objects.

	When  you want to iterate over the same array multiple times you need to instantiate ArrayObject and let it create ArrayIterator instances
       that refer to it either by using foreach or by calling its getIterator() method manually.
