Answer 1

$arr3=array(
"m"=>array("mm"."mmm","mmmm"),
"j"=>array("jj"."jjj","jjjj"),
"s"=>array("ss"."sss","ssss")
);
这个怎么输出呢？不用var_dump和print_r,用for循环或者foreach。。。。谢谢了

Answer 2

function printArr ($families){

if(is_array($families)){
foreach( $families as $key => $val){
if(is_array( $val)) printArr( $val);

else {
echo $key.'==='.$val;

}

}

}

}

print_r()这个就可以啊还有var_dump()也是可以的

$arr = array();
foreach($families as $key=>$val){
$arr[$key]=$val;
}
var_dump($arr);
