Working with arrays

[FVxSF]

Not like, "how do you make one" (well kinda), or "how do you get last item".. Here's my problem, I working on a nice little script to read server stats from a battlefield 2142 server. So far what I have is working really really good, but then I get a little quirk. For and example What I'm doing is creating an array by exploding. All the information about the server players is in one long string so what I have done is convert the identifiers to a unique group then explode based on the group say _::_ for an example.

 

This works great because now I have all the player, pings, kills and so on in one array but every once in a while I'll get the identifier 2 time. Like below say:

 

ping_ 54 75 25 75 kills_ 5 4 7 8 7 kills_ 6 7 5 1

 

Now I'm using the str_replace to replace the identifiers (in this case ping_ and kills_) but when I go to explode the players string the data get screwed up because kills_ is there 2 times.

 

So my question is, how can I combine the 2 kills_ in to the same array?

I don't fully understand what you mean. Perhaps if you provided the code that you have relevant to the question, I may be able to assist you. Unless anybody else could offer me a bit of clarity?

I see your problem, but why does it sometimes return two kills? Which would you need to actually use in that case aswell?

If "kills_" or what ever is stored as an array key, then PHP should display an error if it exists twice (could be wrong). Regardless though, from my experience, if it's a key then the first array element will be overwritten by the second.

This is a little confusing I know. I'll show you what I'm working with:

 

<?php

$sock = fsockopen("udp://". $_GET[ip], 29900);
socket_set_timeout($sock, 0, 750000);

$end = false;
@fwrite($sock, "\xFE\xFD\x09\x01\x01\x01\00");
while( !$end ) {
	$bytes = @fread($sock, 1);
	$sock_status = @socket_get_status($sock);
	$length = $sock_status[unread_bytes];

	if( $length ) {
		$reply = $bytes . fread($sock, $length);
		$challenge = explode("\x00", $reply);
		$challenge_reply = str_split(dechex($challenge[1]), 2);
		$sock_challenge = chr(hexdec($challenge_reply[0])). chr(hexdec($challenge_reply[1])). chr(hexdec($challenge_reply[2])). chr(hexdec($challenge_reply[3]));
	}
	if( $length == 0 ) { $end = true; }
}
@fwrite($sock, "\xFE\xFD\x00\x01\x01\x01\00". $sock_challenge ."\xFF\xFF\xFF\x01");
$end = false; $data = "";

while( !$end ) {
	$bytes = @fread($sock, 1);
	$sock_status = @socket_get_status($sock);
	$length = $sock_status[unread_bytes];

	if( $length ) {
		$data .= $bytes . fread($sock,$length);
	} else { 
		$end = true;
	}
}
fclose($sock);

if( !$data ) {
	echo "Couldn't get info from server";
	exit;
}

$data=str_replace("\\","",$data);				
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(0).chr(0),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(128).chr(0),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(129).chr(1),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(129).chr(2),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(130).chr(1),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(130).chr(2),"",$data);
$data=str_replace(chr(0).chr(1).chr(1).chr(1).chr(0)."splitnum".chr(0).chr(1).chr(1),"",$data);
$data=str_replace(chr(0).chr(0).chr(0),chr(0),$data);

$PInf = substr($data, strpos($data, "player_"), strpos($data, "team_t") - strpos($data, "player_"));

$RplArray = array( // Replacement Array \\
			"player_". chr(0).chr(0) => "",
			"score_" => "::",
			"ping_" => "::",
			"team_" => "::",
			"deaths_" => "::",
			"pid_" => "::",
			"skill_" => "::"
);

$PInfT = str_replace(array_keys($RplArray), array_values($RplArray), $PInf);
$PlayerInArr = explode(chr(0).chr(0) ."::". chr(0).chr(0), $PInfT);


echo $PInf;
echo "\n\n<br><br><hr><br><br>\n\n";

echo "<pre>";
echo var_dump($PlayerInArr) ;
echo "</pre>";

?>

 

First, I don't know much about fsock but I know about bytes and so forth.

After receiving the information I'm after I get the player info like this:

 

player_� Vladiemier�=FCW= LordVaderOfFCW�=fcw= ViperTheSniper�score_��0�0�0��ping_��106�50�54��team_��2�2�1��deaths_��0�0�0��pid_��120276091�65616121�84831881��skill_��0�0�0�

 

Now above there are byte values of 0 "chr(0)" as the serperator, there are 2 bytes after ping_ and player_ and so on, both have a value of 0, chr(0) if you will.

 

Now this is some example of what I need to fix:

 

pid_ chr(0) chr(0) 13294453 "chr(0)" 1�146236060 "chr(0)" �154316543� chr(0) 93162469�10 chr(0) 2633384� chr(0) 157920896 chr(0) pid_136585560� chr(0) 91831085��

 

I added chr(0) as the seperator, but this will happen from time to time. You can try this link -> http://fvxsf.com/archive/fetcher.php?ip=69.12.25.110

you many need to refresh until you see data. Also I changed player_ score_ and so on to :: so if you see :: that mean something like pid_ came up 2 times.

As a follow up, I did manage to fix this problem. What I saw was that there were 2 bytes padding the left and right of the player_ score_ and so on, so I what I did was explode my array based on that because if I did get a stray score_ the left padding was missing 1 byte. So to fix that what I was create an array and used str_replace to trim out what I don't what.

 

Now that I have this fixed, I'm noticing something every now and then. Some times a letter of a name will turn out to be some random byte but if that page is refreshed it goes away.

 

Is there a way to take the byte strings and convert them from raw upd data to something like ascii or utf8?

 

Here is an example:
