PHP код:

new IsPlaying[MAX_PLAYERS]; // up top in your script somewhere
CMD:ehr(playerid) 
{ 
    if(PlayerLogged[playerid] == 0) return 1;
    if(IsPlaying[playerid] == 0)
    { 
         PlayAudioStreamForPlayer(playerid, "http://stream.europeanhitradio.lv"); 
         IsPlaying[playerid] = 1;
    } 
    else 
    { 
         StopAudioStreamForPlayer(playerid); 
         IsPlaying[playerid] = 0;
    } 
    return 1; 
}
