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 RecursiveArrayIterator class

INTRODUCTION

	This  iterator	allows	to  unset and modify values and keys while iterating over Arrays and Objects in the same way as the ArrayIterator.
       Additionally it is possible to iterate over the current iterator entry.

       ArrayIteratorRecursiveIterator

       Methods

       o public RecursiveArrayIterator RecursiveArrayIterator::getChildren (void  )

       o public bool RecursiveArrayIterator::hasChildren (void	)

       o public void ArrayIterator::asort (void  )

       o public ArrayIterator::__construct ([mixed  $array = array()], [int  $flags])

       o public int ArrayIterator::count (void	)

       o public mixed ArrayIterator::current (void  )

       o public array ArrayIterator::getArrayCopy (void  )

       o public void ArrayIterator::getFlags (void  )

       o public mixed ArrayIterator::key (void	)

       o public void ArrayIterator::ksort (void  )
