Example #1 NoRewindIterator::rewind() example

This example demonstrates that calling rewind on a NoRewindIterator object has no effect.

  <?php
$fruits  = array( "lemon" ,  "orange" ,  "apple" ,  "pear" );

 $noRewindIterator  = new  NoRewindIterator (new  ArrayIterator ( $fruits ));

echo  $noRewindIterator -> current () .  "\n" ;
 $noRewindIterator -> next ();
 // now rewind the iterator (nothing should happen)
 $noRewindIterator -> rewind ();
echo  $noRewindIterator -> current () .  "\n" ;
 ?>

以上例程会输出：

lemon
orange
