示例
示例 #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";
?>以上示例会输出：
lemon orange
