foreach 赋值 二维数组
foreach ($menu as $k=>$v){
$arr[]['mid'] = $k;
$arr[]['num'] = $v;
}
print_r($arr);
输出:
Array ( [0] => Array ( [mid] =>9999 ) [1] => Array ( [num] => 1 ) ) 
而不是
Array ( [0] => Array ( [mid] =>9999 [num] => 1 ) )??

为什么? 请教啊。 跟我想的不太一样,想不通啊,现在还在线。。。

------解决方案--------------------

PHP code
foreach ($menu as $k=>$v){
     $arr[]=array('mid' =>$k, 'num' =>$v);
}
