<?php
function compare ($a, $b) {
if ($a == $b) return 0;
return ($a > $b) ? -1 : 1;
}
in that example explaining how to use the function 'usort()', this part of the code
'return ($a > $b) ? -1 : 1; ' is not correct because it must return '-1' if
'$a < $b' and but not if '$a > $b' as written.
Thank you to confirm me that.
Sincerely
