No, you can’t.

~~if(4 <= $a <= 44)will (I believe) be parsed as if ((4 <= $a) <= 44), which checks that (4 <= $a)(i.e. 0 or 1) is less than 44.~~

No, you cannot do this.

if(4 <= $a <= 44)equivalent to if((4 <= $a) <= 44). This may be equivalent to if(false <= 44)or if(true <= 44), none of which makes sense.
