The function signature shows the second parameter has a default value of ‘raw’, but I am not able to find any documentation for all possible values of that second parameter ($filter) as I can for the first parameter ($show).
Does such documentation exist? If so, where can I find it?
I realize I could always read the code definition for the function to try to discover what I’m looking for, but that approach (in general) would obviate the entire codex.
