check if player is staff

[callimuc]

hey i wanted to ask if there is such a command that checks if a player is staff written in the server options (so i don´t use like

PHP Code:

if (player.guild == "Owner") {
blabla
} 


since i think it would make the script too long to add all staff)

i hope there is such a command since i thought i have already seen it somewhere but could find it. it was like:

PHP Code:

function onCreated() {
  is.staff();
}
function onis.staff() {
  //here the script ´looked´ up in the serverv options
  //if the player is a staff member;
} 


i hope i was clear enough what exactly i need
