Array Functions II 7/8


#1

I dont know what to do at 7/8.
I tired this:
$the_array = array(7, 5, 9, 6);
sort($the_array);
print join(", ", $the_array);
?>
<?php
// Reverse sort your array and print the joined elements to the screen
rsort($the_array);
print join(":", $the_array);
?>
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() !
I cut some codes. So dont wonder.
Thx ahead
