title: Check if a number completely divides by 4
body: <p>I need to know if a changing number divides completely by 4. this is the code that I am currently using:</p>
  
  <pre><code>if ($ResultsCounter %4 != 0){
          $htmlResult .=  "&lt;/div&gt;&lt;div class='row'&gt;"; 
      }
  </code></pre>
  
  <p>Problem here is that if the number is greater than 0 it will always divide by 4. I need this to run if the result is a whole number... i.e. 4, 8, 12, 6...</p>
