Return specific value from two level array

Question

Let say if I got a set of array value which is

$array1=array(
“i1” => array(“v1” ,”v2”, “v3”)
, “i2” => “v4”
, “i3” => array(
[0] => “v5”
, [1] => “v6”
, [2] => “v7”
)
, “i4” => array(
[“i5”] = > “v8”
, [“i6”] => array(“v9”,”v10”)
)
)

How do I write to get the result of v3?

Thanks, it work already, because what I type was echo $array1["i1"][3]; — Beginner, Mar 13 '17 at 05:06
What if I was to get v6? Why echo($php_array["i3"][1]); is not working? — Beginner, Mar 13 '17 at 05:10
But I don't want to loop, I want the specific value, is it still necessary using the foreach loop? I thought foreach is used only when I want it to loop. — Beginner, Mar 13 '17 at 05:49

Try this

echo $array1["i1"][2];

i1 is also an array with 3 value where v3 have 2 number index

is there getting any error when you try to get v6 with using echo($array1["i3"][1]);? – Mithu CN Mar 13 '17 at 05:35
Yes, the error that occur was " Undefined offset: 1 " – Beginner Mar 13 '17 at 05:37
this isn't a right way to define an array . Why did you use third bracket in i3 array ? replace [1] => “v6” with 1=>"v6". replace all of those which belong to this format . – Mithu CN Mar 13 '17 at 06:01
