Yep. The modulus operator (%). Your number mod 2 will be 1 if it is odd
and 0 if it is even.
function isOdd ($value) {
return (int)$value % 2 ? true : false;
}
Returns true/false if the value is odd. Also rounds down floating point numbers given
as the test value.

No need to explicitly state true and false. Just

(1 number) ? odd : even;
E.g.
?php
$i=1;
echo 'pre';
while($i 10) {
(1 $i) ? print($i . ' is odd') :

Jake,

I have two people checking the same email address. I want to break up the
emails 50/50 to each person. What values can I put into the random number
generator so that I can get closer to 50/50. I just set up a test page with:

Can you just set a value somewhere (in a flat file, or a database) to 1 or
2. 1 can represent person number 1, 2
