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
