Solved!

I changed it like this:

PHP код:

CMD:kill(playerid)
{
    if(team[playerid] == TEAM_HUMAN)
    {
        SetPlayerHealth(playerid,0.0);
        SendClientMessage(playerid,-1,""chat" You've killed yourself");
        SetPlayerTeam(playerid,TEAM_ZOMBIE);
        team[playerid] = TEAM_ZOMBIE;
    }
    else return SendClientMessage(playerid,-1,""chat" You cannot kill yourself if you are an 'Zombie'");
    return 1;
}
