遍历数组

  • 数组 array[ ] , 0 开始
  • foreach ($array as $b)
  • foreach ($array as $id => $b )

微信公众号开发之(30)遍历数组
核心代码如下:


                $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
                $fromUsername = $postObj->FromUserName;
                $toUsername = $postObj->ToUserName;
                $keyword = trim($postObj->Content);
                $time = time();
                $url="http://222.206.65.12/opac/search_rss.php?dept=ALL&title={$keyword}&doctype=ALL&lang_code=ALL&match_flag=forward&displaypg=20&showmode=list&orderby=DESC&sort=CATA_DATE&onlylendable=no";
                 $fa=file_get_contents($url);
                 $f=simplexml_load_string($fa);
                 foreach ($f->channel->item as $reply)
                 {  
                 foreach ($reply->title as $re)
                    {
                        $a[]=$re;
                    }
                 }
                $no=count($a);

                if ($no>8)
                {
                    $no=8;
                }

                $textTpl = "<xml>
                            <ToUserName><![CDATA[%s]]></ToUserName>
                            <FromUserName><![CDATA[%s]]></FromUserName>
                            <CreateTime>%s</CreateTime>
                             <MsgType><![CDATA[news]]></MsgType>
                             <ArticleCount>$no</ArticleCount>
                             <Articles>";
                foreach($a as $id=>$b)
                {
                    if($id>$no) break; else null; 

                    $textTpl.="<item>
                                     <Title>$b:</Title> 
                                     <Description><![CDATA[$s]]></Description>

                                </item>";
                 }
                $textTpl.="</Articles>
                             <FuncFlag>1</FuncFlag>
                            </xml>";             

                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time);
                echo $resultStr;

index.php整体代码如下:
