Does this function excist

[Guest]

I'm have an if statement and I want to do something like this.

 

if($post == 5 - 10)) //five through ten
{then do this}

Is there a function or different method to do this?

 

If not, I'm guessing I'll have to make the function.

if($post >= 5 && $post <= 10)) //five through ten
{then do this}
