CachingIterator::getCache — Retrieve the contents of the cache
此函数没有参数。
An array containing the cache items.
Throws a BadMethodCallException when the
CachingIterator::FULL_CACHE
flag is not being used.
示例 #1 CachingIterator::getCache() example
<?php
$iterator = new ArrayIterator(array(1, 2, 3));
$cache = new CachingIterator($iterator, CachingIterator::FULL_CACHE);
$cache->next();
$cache->next();
var_dump($cache->getCache());
$cache->next();
var_dump($cache->getCache());
?>
以上示例会输出:
array(2) { [0]=> int(1) [1]=> int(2) } array(3) { [0]=> int(1) [1]=> int(2) [2]=> int(3) }
