php 遍历数组 只显示1个,求高手指点，foreach遍历三维数组时只能遍历出第一个子级，这是为什么呢？...
$val){?>
=$val['id']?>οnclick="task(=$val['id']?>,'=$val['name']?>')">=Util::msubstr($val['name'],0,16,'gbk')?>=date("Y-m-d ",strtotime($val['date_start']))?>=$val['plan_director_name']?>
=$v['id']?>=Util::msubstr($val['name'],0,16,'gbk')?>=1?>=date("Y-m-d ",strtotime($v['date_start']))?>=$val['plan_director_name']?>=$v['status']?>}}}}?>
回复讨论(解决方案)
三维数组需要三个foreach嵌套遍历才可以。
但是我第一个父节点下的子节点能遍历出来啊
不是特别清楚你的数据结构，检查一下这个条件有没有满足
if(is_array($val[$key]))
你的外层循环是
foreach($monitorList as $key=>$val)
进入内层循环的条件是
if(is_array($val[$key]))
不符合条件时，自然就没有输出
你至少应
var_export($monitorList);
贴出结果看看

看到这结果就昏了
if (is_array($val)) { //判断$val的值是否是一个数组，如果是，则进入下层遍历
??是
if (is_array($val)) 判?是否有下一?
谢谢各位大侠的指点错误原因找到了，后台压数据时没指定下标，直接$monitorList[$key][]=query($sql);导致前台遍历出错。
给个下标就搞定了。
