Code:

COMMAND:clan(playerid, params[])
{
	new cmd[20];
	if(sscanf(params, "s[20]", cmd))
	{
	    return SendClientMessage(playerid, COLOR_DGOLD, "CMD: /clan <weapons/leader/members/rank/base>");
	}
	if(strcmp(cmd, "weapons", true) == 0)
	{
	    //Weapon Code
	}
	if(strcmp(cmd, "leader", true) == 0)
	{
	    //Leader Code
	}
	if(strcmp(cmd, "members", true) == 0)
	{
	    //Members Code
	}
	if(strcmp(cmd, "rank", true) == 0)
	{
	    //Rank Code
	}
	if(strcmp(cmd, "base", true) == 0)
	{
	    //Base Code
	}
 	return 1;
}

In PlayerInfo array make Member/Leader variable and setup your gangs by making Member = PD (for example)

And use that code for Base entering, car entering, invite code where you set /clan invite [playerid] [id] and PlayerInfo[playerid][Member] = 1 etc...

Or use some finished systems...
