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
