You can display the value by reading the key of the array. In side the function you can see one for loop is used with variable i, if i value is taken from user then the corresponding value can be displayed.

how about, if the data in the arrays are on the table? what will the code format is?
While displaying the data you can use the array push to insert data to the JavaScript array. Note that while using server side script you have to echo or print the client side JavaScript code to store values inside array.
