well you have to say more, do you ant to do something if it is greater than one or not, if you want od do something if it is greater than one you could use an if statement like...
if($num > 1)
{
print("$num is greater than 1");
}
else
{
print("$num is less than 1");
}
like that, but then again im not sure what it is that you wnat ot do.
