I need to get that by using the for each function

Hi all,

{1,2,3,8,9,9,9,9,9,80,90,70}, {56,76,54,32}, {20,23,45,54,32,54}, {1,2,3,4,5,6,7}, {11,12,13,14,15,16,17,18}

Please suggest how do this using foreach function get output like this,

length of array 1 is 12
length of array 2 is 4
length of array 3 is 6
length of array 4 is 7
length of array 5 is 8
