Catch selected checkboxes and turn them in to variables in php

Question

I'm stuck with the following:
I have 2 rows of checkboxes with different names.
HMTL Example:

<form action="" method="POST" enctype="multipart/form-data"> 
    <div id="firstrow"> 
        <input type="checkbox" name="first" value="1">1 
        <input type="checkbox" name="first" value="2">2
        <input type="checkbox" name="first" value="3">3
        <input type="checkbox" name="first" value="4">4
     </div>
     <div id="secondrow"> 
        <input type="checkbox" name="second" value="1">1 
        <input type="checkbox" name="second" value="2">2
        <input type="checkbox" name="second" value="3">3
        <input type="checkbox" name="second" value="4">4
     </div>
 </form>

The user is only allowed to select 2 checkboxes per row of checkboxes (I found a small JS code that allows me to do this).
In total they will have selected 4 checkboxes, now I want to enter all 4 of these values in to a database in separate columns.
Now I have looked up ways to convert these values in to variables, I came across one which looped a little script that checked if each checkbox was checked or not, but in the end none of all that worked the way I wanted it to.
At the moment I'm completely stuck at this point, but I'm sure there might be a somewhat easy solution to this problem that I'm completely looking over!
Now I'm asking if anybody can help me with a couple of tips or perhaps a few search terms that I could try to get me going on this problem again.

Thanks a lot in advance!

Put square brackets around the name (so first[] and second[]) and you'll have all the checked boxes at your disposal in the $_POST-array (an array for each set of checkboxes).
