Hello, I'm not sure what's wrong with this code. I keep getting the error "Your reverse sorted array should have at least 3 elements in it. Make sure to pass a comma as the first argument to join() !" however, there are four things in the array. Thanks!
<html> <p> <?php // Create an array and push 5 elements on to it, then // print the number of elements in your array to the screen $the_array = array(5, 3, 7, 1); sort($the_array); print join(',', $the_array) . "<p></p>"; rsort($the_array); print join(',', $the_array); ?> </p> </html>
