如果我还想再加一个数组,第23行应该怎么表达?
<?php $students = array( '2010'=>array('令狐冲'=>array('a','b'),"59"), '2011'=>array('林平之',"44"), '2012'=>array('曲洋',"89"), '2013'=>array('任盈盈',"92"), '2014'=>array('向问天',"93"), '2015'=>array('任我行',"87"), '2016'=>array('冲虚',"58"), '2017'=>array('方正',"74"), '2018'=>array('岳不群',"91"), '2019'=>array('宁中则',"90"), );//10个学生的学号、姓名、分数,用数组存储 foreach($students as $key=>$val) { //使用循环结构遍历数组,获取学号 echo $val; //输出学号 echo "<br />"; //循环输出姓名和分数 foreach($val as $key1=>$v) { echo $v; //判断下下层是不是数组,在进行遍历 if(is_array($v)){ foreach($v as $vv) { echo $vv; echo "<br />"; } } echo "<br />"; } echo "<br />"; } ?>
