PHP value not between two numbers

Question

Right now I have the following code:

if ($costOne <> $costTwo) {}

and I'd like to change this to

if ($costOne is not within the range of $costTwo - .0001 and $costTwo + .0001) {}

I've tried writing this a few different ways but I'm not doing something right.... can someone provide me the correct syntax to express this?

Just have two conditions in your if statement. One that checks the low value, ne for the high — John Conde, Nov 25 '14 at 14:30
Usually, with float checking: `if(abs($first - $second) < $allowed_difference))` — Wrikken, Nov 25 '14 at 14:33

You basically had it:

((($costTwo - 0.0001) <= $costOne) && ($costOne <= ($costTwo + 0.0001)))

Or, alternatively

(abs($costOne - $costTwo) <= 0.0001)

I like the abs way then it's possible and useful :D – Marco Mura Nov 25 '14 at 14:32

You can do it like below:

$lowerbounds = $costOne - .0001;
$higherbounds = $costOne + .0001;
if($costOne < $lowerbounds || $costOne > $higherbounds){ ....
