【问题描述】：

我在一个关联数组中存储了许多数组，并为键值分配了简单的数字计数。

如何从关联数组中提取其中一个数组？

我的数组：

$arr = array(
        1 => array("ask","bat","cod","dig","egg","fur","gap","hay","ice","jar","kin","lee"), 
        2 => array("add","big","cap","day","eye","fat","gel","hop","ink","jog","key","law"),   
        3 => array("axe","bin","cel","don","eat","fig","gig","hut","ion","jin","kid","lip")
    );

我想将索引为 2 的数组存储在 $arr_chosen 中，这样做的语法是什么？

【问题讨论】：

$arr_chosen=$arr[2];
