I'm not quite sure I understand what you're trying to do, but why not use strcmp?

PHP код:

CMD:test_id(playerid, params[]) 
{ 
    new targetid[4];
    if(sscanf(params,"s[4]", targetid)) return 1; // exit
    for(new i; i <= MAX_PLAYERS; i++) {
        if(!strcmp(targetid, GetName(i), false, 4)) printf("Player's ID %i - Name: %s", i, GetName(i)); }
    return 1;
}
