請(qǐng)問(wèn)這段代碼哪里有錯(cuò)？$newsArr?=?array(
?????????array("Title"=>"this?is?first?item",
????????????"Description"=>"this?is?first?item?description",
????????????"PicUrl"=>"http://img4.imgtn.bdimg.com/it/u=2943793272,3641314298&fm=21&gp=0.jpg",
????????????"Url"=>"http://www.baidu.com"
?????????),
?????????array("Title"=>"this?is?second?item",
?????????????"Description"=>"this?is?second?item?description",
?????????????"PicUrl"=>"http://img2.imgtn.bdimg.com/it/u=945726929,542696667&fm=21&gp=0.jpg",
?????????????"Url"=>"http://www.baidu.com"
?????????),
?????????array("Title"=>"this?is?thired",
????????????"Description"=>"this?is?thired",
????????????"PicUrl"=>"http://img1.imgtn.bdimg.com/it/u=2783016379,35786742&fm=21&gp=0.jpg",
????????????"Url"=>"http://www.baidu.com"
?????????)
);
foreach?($newsArr?as?$key?=>?$value)?{
???$itemstr?.=?"
?????????<item>
?????????<Title><![CDATA[".$value['Title']."]]></Title>
