title: How do I explode an integer
body: <p>the answer to this could be easy. But I'm very fresh to programming. So be gentle...</p>
  
  <p>I'm at work trying to do a quick fix for one of your customers. I want to get the total numbers of digits in a integer, and then explode the integer:</p>
  
  <pre><code>rx_freq = 1331000000 ( = 10 )
    $array[0] = 1
    $array[1] = 3
    .
    .
    $array[9] = 0
  
  rx_freq = 990909099 ( = 9 )
    $array[0] = 9
    $array[1] = 9
    .
    .
    $array[8] = 9
  </code></pre>
  
  <p>I'm not able to use explode, as this function need a delimiter. I've searched the eyh'old Google and Stackoverflow.</p>
  
  <p>Basically: How do I explode an integer without delimiter, and how do I find the number of digits in an integer.</p>
