Here's an even simpler pair of functions for finding out if a number is odd or even:
function IS_ODD($number) { return($number & 1); }
function IS_EVEN($number) { return(!($number & 1)); }
Test:
$myNumber = 151;
if(IS_ODD($myNumber))
echo("number is odd\n");
else
echo("number is NOT odd\n");
if(IS_even($myNumber))
echo("number is even\n");
else
echo("number is NOT even\n");
Results:
number is odd
number is NOT even
