Where did you put those codes ?

and try these if works or nop

Код:

new string[128], pName[MAX_PLAYER_NAME];
GetPlayerName(playerid,pName,MAX_PLAYER_NAME);
format(string,sizeof(string)," %s has joined the server",pName);
SendClientMessageToAll(-1,string);

Edit: or use this one, should work

Код:

for(new i = 0, j = GetPlayerPoolSize(); i <= j; i++) 
    {
     new string[128],pName[MAX_PLAYER_NAME];
GetPlayerName(playerid,pName,MAX_PLAYER_NAME);
format(string,sizeof(string),"%s has joined to the server",pName);
SendClientMessage(i,-1,string);
     }
