How to find if a number is odd or even?
In PHP I learn to use the MOD (%) operator. see below for an example:
$i = 10;
if ($i % 2) {
echo "$i is odd";
} else {
echo "$i is even";
}
You can also use the PHP "&" operator that will give you better
performance
You can use the PHP code like so:
$i = 10;
if ( $i&1 )
{
echo "$i is odd";
}
else
{
echo "$i is even";
}
