PHP foreach()跳出本次或当前循环与终止循环方法

1、php foreach()跳出本次或当前循环与终止循环方法phpforeach()跳出本次或当前循环与终止循环办法php中用foreach()循环中，想要在循环的时候，当满足某个条件时，想复制代码$arr=array(&39;a&39;,&39;b&39;,&39;c&39;,&39;d&39;,&39;e&39;);$html=&39;&39;foreach($arras$key=>$value)if($value=&39;b&39;)$html.=$value;contin

2、ue;/当$value为b时，跳出本次循环if($value=&39;c&39;)$html.=$value;break;/当$value为c时，终止循环$html.=$value;echo$html;/输出：ab复制代码下面是自己的实际例子/父级栏目publicfunctionparentlist($id)/查询该栏目下全部子类数据$categorydata=db("category")->where("id=".$id)->find();/dump($categorydata);if(!$c

3、ategorydata)$this->error("参数错误");else$this->assign(&39;categorydata&39;,$categorydata);/查询该栏目下全部子类数据即pid=$id$category=db("category")->select();$praproductdata=$this->tolayer($category);/dump($praproductdata);foreach($praproductdataas$k=>$v)/

4、假如有子类目if(!empty($v&39;zilei&39;)&&$v&39;id&39;=$id)$praductdata=db:table("ven_article")->alias(&39;a&39;)->join(&39;ven_categoryw&39;,&39;a.cid=w.id&39;)->where("a.status=1andw.pid=&39;".$id.&

5、;quot;&39;")->field("a.id,a.title,a.faceimg,a.time_report,a.resume,a.cid,")->order(&39;a.iddesc&39;)->paginate(6);/dump($praductdata);break;else/没有子类if($v&39;id&39;=$id)$praductdata=db:table("ven_article")->alias(&

6、;39;a&39;)->join(&39;ven_categoryw&39;,&39;a.cid=w.id&39;)->where("a.status=1anda.cid=".$id)->field("a.id,a.title,a.faceimg,a.time_report,a.resume,a.cid,")->order(&39;a.iddesc&39;)->paginate(6);/dump($praductdata);b

7、reak;$data=$praductdata->toarray()&39;data&39;/或者$data=$praductdatas->all();if($data)$this->assign(&39;a&39;,1);$page=$praductdata->render();$this->assign(&39;page&39;,$page);$this->assign("newpraproduct",$praductdata);returnview("

8、parentlist");打印$praproductdata结果如下：array(5)0=>array(9)"id"=>int(1)"pid"=>int(0)"path"=>string(3)"0-1""name"=>string(9)"风幕柜""status"=>int(1)&quo
