Use strtok, a lot easier.

pawn Код:

//OnPlayerCommandText
    new cmd[128], idx;
    cmd = strtok(cmdtext, idx);

    if(!strcmp("/playername", cmd)) {
        new tmp[128];
        tmp = strtok(cmdtext, idx);
        if(!IsPlayerConnected(strval(tmp))) return SendClientMessage(playerid, COLOR_RED, "ERROR: Invalid player.");
        new name[MAX_PLAYER_NAME];
        GetPlayerName(strval(tmp), name, sizeof(name));
        new message[128];
        format(message, sizeof(message), "RESPONSE: ID: %i | Player Name: %s", strval(tmp), name);
        SendClientMessage(playerid, COLOR_GREEN, message); 
        return 1;
    }

Try that, if you get errors about not having strtok, put this at the bottom of your script:

pawn Код:

strtok(const string[], &index)
{
    new length = strlen(string);
    while ((index < length) && (string[index] <= ' '))
    {
        index++;
    }
 
    new offset = index;
    new result[20];
    while ((index < length) && (string[index] > ' ') && ((index - offset) < (sizeof(result) - 1)))
    {
        result[index - offset] = string[index];
        index++;
    }
    result[index - offset] = EOS;
    return result;
}
