Dear monks, thanks for your insights and extensions!

I did this one-liner as a fun task (because i was too lazy to detect min and max values beforehand) while working with integer values.

I agree with syphilis and LanX that

$inRange = (($a <=> $x) * ($b <=> $x)) <= 0;

is the most canonical form, where <= emphasizes the inclusion of the limits while < would hint for the exclusion.

My previous attempt was

$inRange = ($x > $a == $x < $b) || $x == $a || $x == $b; (inclusive)
$inRange = ($x > $a == $x < $b); (exclusive)

which seemed less elegant, but the exclusive version might be faster.

Cheers, Heiko
