It is correct to use $i%2 to get even and odd program control HOWEVER using bit level operators is better, faster and more effecient so TO get odd and even $num&1 is much better To NULL any element $element^$element is also much better For New comers these functions are based on the binary representation of variables in memory. It so happens that an even number always has a 0 on the end, and an odd number always has a 1 on the end so 1010101 & 0000001 is true ---- Manual Page -- http://www.php.net/manual/en/function.bcmod.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+35853 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+35853&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+35853&report=yes
