AdminSkin, ..., AdminSkin10 might be an array. And then you do like this:

PHP код:

new bool:check = false;
for(new i = 1; i < 11; i++)
    if(GetPlayerSkin(playerid) == ServerInfo[AdminSkin[i]])
    {
        check = true;
        break;
    }
if(check)
{
    // Your code
} 


But, in your example, try this:

PHP код:

    if(ServerInfo[AdminOnlySkins] == 1)
    {
        new skin = GetPlayerSkin(playerid);
        if((skin == ServerInfo[AdminSkin]) || (skin == ServerInfo[AdminSkin2]) ||
        (skin == ServerInfo[AdminSkin3]) || (skin == ServerInfo[AdminSkin4])   ||
        (skin == ServerInfo[AdminSkin5]) || (skin == ServerInfo[AdminSkin6])   ||
        (skin == ServerInfo[AdminSkin7]) || (skin == ServerInfo[AdminSkin8])   ||
        (skin == ServerInfo[AdminSkin9]) || (skin == ServerInfo[AdminSkin10]))
        {
            if(AccInfo[playerid][Level] >= 1)
            GameTextForPlayer(playerid,"~b~Welcome~n~~w~Admin",3000,1);
            else
            {
            GameTextForPlayer(playerid,"~r~This Skin Is For~n~Administrators~n~Only",4000,1);
            SetTimerEx("DelayKillPlayer", 2500,0,"d",playerid);
            return 1;
            }
        }
    }
    if((dUserINT(PlayerName2(playerid)).("UseSkin")) == 1)
        if((AccInfo[playerid][Level] >= 1) && (AccInfo[playerid][LoggedIn] == 1))
        SetPlayerSkin(playerid,(dUserINT(PlayerName2(playerid)).("FavSkin")) );
