在php中从较大的关联数组中提取数组

Question

I have stored many arrays in a single associative array and assigned key values simple number counting.

How can I extract one of those array from the associative array?

my array:

$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")
    );

I want to store the array indexed say 2 in $arr_chosen , what will be the syntax to do so?

$arr_chosen = $arr[2];
