in reply to passing a value to a function

ishmael
$array = [ ] ;

is sufficient. This will effectively "clear" the array. Depending on your requirements, $i=[ 0 ] , $i=undef ], and $i may be all equivalent.

Remember that undef is actually an array element. I have caught myself thinking that @array = (undef) is an empty array. Nope. It is a single-element array with the element undef!

    Nope, it will not clear the array!
    Instead it will create a new, empty anonymous array and store a reference to that in $array.
