[PHP] I need help with retrieving values in arrays

Hi guys!

I have an array called services, in the services array, it holds an array of keys and values, for example title, overview etc. In one of the key called sub-services, I have an array of sub-services such as "Logos, "Business Cards".

The way i display my services in my page is through rows and columns. I am using Foundation 3 by Zurb.

I want to make a function to dynamically display my services from the array.

  1. I am able to specify how many columns I want the portfolio to be.

Foundation 3 works on 12 columns, If i want to have 3 service per row, each service has to be 4 columns. How do i make the loop so that if I specified to have a 3-column layout, It will count the total of sub-services of the service, for the first 3 services, put them in the first row, for the next 3 services, put them in the next row and the next few services in the new row, and so on.

Also, how do i make it so that, if the remainder does not equate to 3, then i will have to give it a class of "end" at the last service so that it doesn't float all the way to the right?

You want to use the modulus operator, a percent sign (%):

echo 1 % 3; // 1
echo 2 % 3; // 2
echo 3 % 3; // 0
echo 4 % 3; // 1

You want something like this:

if (($i % 3) == 0) {
    echo "end";
}

Here's a link to the PHP manual with that operator: http://php.net/manual/en/language.operators.arithmetic.php

Does that help?
