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方法

php中用foreach()循环中，想要在循环的时候，当满足某个条件时，想

$arr = array('a','b','c','d','e');$html = '';foreach($arr as $key => $value){    if($value=='b'){        $html .= $value;        continue; // 当 $value为b时，跳出本次循环    }    if($value=='c'){        $html .= $value;        break; // 当 $value为c时，终止循环    }    $html .= $value;}echo $html; // 输出： ab

下面是自己的实际例子

//父级栏目    public function parentlist($id)    {        //查询该栏目下所有子类数据        $categorydata = db("category")->where("id=".$id)->find();        //dump($categorydata);        if(!$categorydata){            $this->error("参数错误");        }el{            $this->assign('categorydata',$categorydata);            //查询该栏目下所有子类数据即 pid=$id            $category = db("category")->lect();            $praproductdata = $this->tolayer($category);　　　　　　　//dump($praproductdata);            foreach($praproductdata as $k=>$v) {                //如果有子类目                if (!empty($v['zilei']) && $v['id']==$id) {                    $praductdata = db::table("ven_article")                        ->alias('a')                        ->join('ven_category w','a.cid=w.id')                        ->where("a.status=1 and w.pid='".$id."'")                        ->field("a.id,a.title,a.faceimg,a.time_report,a.resume,a.cid,w.name")                        ->order('a.id desc')                        ->paginate(6);                        //dump($praductdata);                        break;                }el{                    //没有子类                    if ($v['id'] == $id) {                        $praductdata = db::table("ven_article")    兰蔻面膜                            ->alias('a')                                ->join('ven_category w','a.cid=w.id')                                ->where("a.status=1 and a.cid=".$id)                                ->field("a.id,a.title,a.faceimg,a.time_report,a.resume,a.cid,w.name")                                ->order('a.id desc')                                ->paginate(6);                        //dump($praductdata);                        break;                    }                }            }            $data = $praductdata->toarray()['data'];//或者$data = $praductdatas->all();            if($data){                $this->assign('a',1);            }            $page = $praductdata->render();            $this->assign('page',$page);            $this->assign("newpraproduct",$p熊佳琪raductdata);        }        return view("parentlist");    }　　

打印$praproductdata结果如下：

要跳出本次循环继续执行下次循环，或者满足某个条件的时候，终止foreach()循环，分别会用到：continue 与 break。
