Is there a native php function that tells you whether a number is between x and y... something like this?
Code: Select all
if(between($num, $low, $high)) // Do something
I couldn't find it if it exists

no.
Code: Select all
if (max($num, $low) == min($num, $high))

I'd stick with:
I didn't make any tests, but I'm almost sure it'd be faster than the other solutions because the other solutions mentioned above call to 2 functions, while the above calls non.
Edit:
After
a very short and rough test I can say for sure: Don't use
scottayy's way (no offense of course

).
Second, according to the test, my way is ±8 times faster than
feyd's way. But again, it was a rough test and maybe a better and more serious test will have different results (although I doubt it).
