PHP function parameters defined

When I execute some SQL functions I get a list of possible variables, but cant find any documentation on how to complete something similar.

For example:-
class SimpleClass
    const $lookupA = 1;
    const $lookupB = 2;
    const $lookupC = 3;

    public function displayVar(llookup*) {
        return $lookup*;

Open in new window

So, if I typed myNewClassInstance->displayVar( into my IDE my choices would be lookupA,lookupB or lookupC and would return a value 1-3. This is just a simple class to describe what Im trying to do, its not the best implementation.

Any ideas?
