Question

Currently I’m using the following approach to determine if $userlevel is either 10, 20, or 30.

if ( in_array( $userlevel, array( 10, 20, 30 ) ) ) { 

} 

Is there a better way to do this?

Answer 1

You are already using the “better way”. The alternative would be

if ($userlevel == 10 || $userlevel == 20 || $userlevel == 30) {

}

Typically you’d write a basic if statement until the number of possible values grows such that the line becomes too long, and then you move them into a collection and use in_array.

If you know that $userlevel will always be one of those values, you could simply test that it’s between the upper/lower bound, but this won’t be any shorter than the way you’re writing it now.
