Warning: Illegal type returned from MultipleIterator::key() in D:\www\mytest\test.php
按照老师的代发,我的运行出来是有这个warning,php版本5.3.28。这是怎么回事呢?

最初的代码如下: $idIter=new ArrayIterator(array('01','02')); $nameIter=new ArrayIterator(array('张三','李四')); $mit=new MultipleIterator(MultipleIterator::MIT_KEYS_ASSOC); $mit->attachIterator($idIter,'id'); $mit->attachIterator($nameIter,'name'); foreach($mit as $key=>$val) { print_r($val); }
以上代码会报warning错误
但是,但我把$key删除过后,就没问题了~
$idIter=new ArrayIterator(array('01','02'));
$nameIter=new ArrayIterator(array('张三','李四'));
$mit=new MultipleIterator(MultipleIterator::MIT_KEYS_ASSOC);
$mit->attachIterator($idIter,'id');
$mit->attachIterator($nameIter,'name');
foreach($mit as $val)
{
print_r($val);
}
