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
