how to test if multiple conditions exist 1

[nfaber]

Hello all. I am trying to use logical ors in an if statement that does not seem to be working. Here is my sample code:

if ($day = 24||25||26||27||28||29||30) {
do something;
}else{
do something else;
}

How do you use multiple ors?

Thanks

Well for numeric values at least, it would be

if ( $day >= 24 && $day <= 30 )

If the values were not continuous, you could use:

if (($day == 24) || ($day == 25) || ... || ($day == 30)

or you could test as a string:

if ($day =~ m/^(24|25|26|27|28|29|30)$/)

"When all else has failed, read the manuals."

For a smallish list of possible values like that, I'd probably grep it:

if(grep $day == $_, 24..30)
