    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
