title: PHP Unset Array value effect on other indexes
body: <p>I am working with a PHP loop, and I had one question regarding how unset affects the array keys. This array uses the standard numeric keys assigned by PHP, <code>0, 1, 2, 3 etc...</code>. Whenever <code>unset()</code> runs on an array value, are the array keys shuffled or are they maintained as before?</p>
  
  <p>Thank you for your time.</p>
