从 php 中更大的关联数组中提取数组

Question

我在一个关联数组中存储了很多数组，并分配了键值进行简单的数字计数。

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")
    );

我想在 $arr_chosen 中存储索引为 2 的数组，这样做的语法是什么？

Answer 1

你可以通过

提取数组

$arr_chosen = $arr[2]

Answer 2

$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")
    );
$arr_chosen = $arr[2];
