Here is a good method,

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    dcmd(heal, 4, cmdtext);
    return 0;
}

dcmd_heal(playerid, params[])
{
    new id Float:amount;
    if (sscanf(params, "df", id,amount))return SendClientMessage(playerid, 0xFF0000AA, "Usage: /heal <playerid> <amount>");
    if(id != INVALID_PLAYER_ID)
    {
        if(amount <= 100.0 && amount >= 1)
        {
            SetPlayerHealth(id,amount);
            return 1;
        }
        else return SendClientMessage(playerid, 0xFF0000AA, "Error: Invalid Amount");
    }
    else return SendClientMessage(playerid, 0xFF0000AA, "Error: Player not found");
}

Not tested but should work.

Edit: Delete that apple fuction all it does is returns 2. Unless for some reason you need that, I cant see why though.
This

pawn Код:

stock apple(playerid)
{
    return 1+1;
}

Might aswell be

pawn Код:

stock apple(playerid)
{
    return 2;
}
