PHP код:

CreateDynamic3DTextLabel(const text[], color, Float:x, Float:y, Float:z, Float:drawdistance, attachedplayer = INVALID_PLAYER_ID, attachedvehicle = INVALID_VEHICLE_ID, testlos = 0, worldid = -1, interiorid = -1, playerid = -1, Float:streamdistance = STREAMER_3D_TEXT_LABEL_SD, areaid = -1, priority = 0); 


Use the parameter "playerid". It set the label only for this players. If you have no clue what is streamer plugin or you don't find how to solve that "problem" ; you should script something simpler.
