This will work:

PHP Code:

CMD:admins(playerid) {
    new string[256], tempstring[56], plName[MAX_PLAYER_NAME];
    foreach(Player, i) {
        if(PlayerInfo[i][pAdmin] != 0) {
            GetPlayerName(i, plName, sizeof plName);
            format(tempstring, sizeof tempstring, "Admin: %s(%d), Rank:%d\n", plName, i, PlayerInfo[i][pAdmin]);
            strcat(string, tempstring, sizeof(string));
        }
        ShowPlayerDialog(playerid, DIALOG_ID, DIALOG_STYLE_MSGBOX, "Admins Online", string, "Okay, "");
    }
    return 1;    
}
