Return variable with the highest value?

I'm trying to come up with a simple way of finding the highest number out of 3 variables.

$1 = 100
$2 = 300
$3 = 200

out of those 3 variables, I want to set a new variable as the highest one ($2)

so:

$highest_number = 300

$highest_number = max($1, $2, $3);

OR

$values = array($1, $2, $3);
$highest_number = max($values);

Additional information can be found at the quickref for max

Thanks, but I have tried this however it returns "Array" instead of the number. :\ – Dylan Cross Aug 09 '12 at 02:38
Should be `array_max($values)` for the array version. – Michael Berkowski Aug 09 '12 at 02:39
@Michael From the PHP Docs: *If the first and only parameter is an array, max() returns the highest value in that array. If at least two parameters are provided, max() returns the biggest of these values.* – Matt Williamson Aug 09 '12 at 02:40
@DylanCross this is definitely the right way to do it. $1, $2 or $3 must be an array. Try `var_dump(max($values));` in order to see waht exactly is in the array. – Matt Williamson Aug 09 '12 at 02:41
