php - 向现有数组添加附加值

Question

我有以下代码:

$tab=array(
    "january"=>array(300,420,530,400),
    "february"=>array(420,440,410,380),
    "march"=>array(330,310,250)
     );

如何向名为“april”的 $tab 数组中添加另一个元素，其值为 280 和 290？

Answer 1

试试这个

$tab=array(
    "january"=>array(300,420,530,400),
    "february"=>array(420,440,410,380),
    "march"=>array(330,310,250)
     );
$tab["april"] = array(280,290);
