Getting info from HTML site

[VipleX]

Yesterday I've posted a question here about file_get_contents. I was using that one, with a regEx to find a string on a website, and from that string get some info. I'll see if I can explain what I want using pictures.

This is a bit from the page I want the info from:
http://img505.imageshack.us/img505/5890/php1de1.png

On there it says:

Game Name Gametype Players
{a.s.u}sniper TDM 4/16

On my site I have this block:
http://img505.imageshack.us/img505/345/php2ju1.png

And this is my current script for that block:
http://asu-clan.info/phpscript.txt

What I want is, to have the amount of players displayed, but only for this "{a.s.u}sniper", not others on this list:
http://nw4.novaworld.net/bhd_3_list.lob?page=0

I'm not sure if this is actually possible... If it is, any help is welcome 🙂

Thanks,

So then why not continue the discussion in your other thread? Why a new thread for the same question. You want screen scraping which can't be trusted always. If possible, get an RSS feed of the data.

I would expect this to work:

<?php

$html = file_get_contents('http://nw4.novaworld.net/bhd_3_list.lob?page=1');

$regex = '~\{a\.s\.u\}sniper.*</td>.*<td><font.*>(.*)</font></td>.*<td><font.*>(.*)</font></td>.*<td><font.*>(.*)</font></td>~iUs';
preg_match($regex, $html, $matches);

var_dump($matches);

That should give you something (hopefully). It's not tested, so not guaranteeing it's 100%.

Sorry, I thought this would be a different kind of question. For future questions I'll keep it in one single topic, Sorry :o

Right now I got this code, which apparently does work, but not properly. When I use it it displays the whole page im trying to get info from, instead of only the amount of players bit.

<?php

$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=0");
$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=1");
$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=2");
$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=3");

$regEx = '/<td><b><font.*><font.*>\{a\.s\.u\}<\/font><font.*>sniper<\/font><\/font><.*><\/td>(.*)<td><font.*>TDM<\/font><\/td>(.*)<td><font.*>PLAYERSHERE<\/font><\/td>/is';
if(preg_match($regEx, $html, $matches)) {
	var_dump($matches);
	$content .=$matches;
} else {
	$content .="Doesn't work!";
}

?>

The bit where it says 'PLAYERSHERE'. I want only that bit displayed. It should be something like '14 of 16', or any other number instead of the 14.

I tried using (.*), but apparently that stands for 'anything' rather than the thing that '$matches' will display. How could I fix this ?

Thanks,

$matches is an array of data. Look at the array. You should see:

$matches[0] being everything that was matched by the regular expression.

$matches[1] should be the first matched sub-group (that defined by "(" ")").

Paste the output of the var_dump() here so we can see it.

[VipleX]

Actually the output is all across my whole site, at the top it says:

array(4) { [0]=> string(1945) " Untitled

Towards the middle it says:

" Untitled --- 1 of 16

Untitled --- 1 of 16

Untitled --- 1 of 16

Untitled --- 1 of 16

Untitled DM 1 of 16

Untitled --- 1 of 16

View the page source. most of that is HTML formatting and that's overshadowing the output of the rest of the var_dump().

or perhaps give a link to your output.

[VipleX]

Sorry you quite confused me there, but here's a link:
http://asu-clan.info/html/index.php

The 'page source', do you mean the site Im attempting to get info from ? It's plain HTML, I checked that in MS Frontpage, then copied the bit i needed to search for in a regex.

[bpat1434]

gimmie about an hour. I'm in class, but I'll look at it when I get home (around 12:30, 50 minutes from now).

Thanks in advance! 🙂

Okay, your regex was messed up. You need to be careful with it. This is why screen-scraping is so difficult and can run you into problems.

So, here's what works for me:

<?php

$html = file_get_contents('http://nw4.novaworld.net/bhd_3_list.lob?page=1');

$regex = '~<td><b>(<font.*>)+\{a\.s\.u\}</font.*><font.*>sniper(</font>)+</b></td>.*<td><font.*>TDM</font></td>.*<td><font.*>(.*)</font></td>~iUs';
preg_match($regex, $html, $matches);
array_shift($matches); // Get rid of the entire html string that was matched
var_dump($matches);

That outputs in the var_dump:

---------- PHP - Execute ----------
array(3) {
  [0]=>
  string(22) "<FONT COLOR="#008000">"
  [1]=>
  string(7) "</FONT>"
  [2]=>
  string(8) "16 of 16"
}

Output completed (0 sec consumed)

Do note that this is the output from a php-cli call from within my text-editor, so you won't see the "--- PHP - Execute ---" or "Output completed..." lines if you run this in your browser.

I see, many thanks ! 😉

Although, above the 'Serverblock' on the left side of my website it now says:

array(3) { [0]=> string(22) "" [1]=> string(7) "" [2]=> string(8) "15 of 16" }

and at the place Inside the block where I want the "15 of 16" (without quotes) displayed, it says 'Array'. How can I fix this ?

[VipleX]

Sorry :o It seems It works good now. It does slow the webpage a little bit, but not enough to take it off. Now I have this code:

<?php

if ( !defined('BLOCK_FILE') ) {
    Header("Location: ../index.php");
    die();
}

$content ="";

$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=0");
$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=1");
$html = file_get_contents("http://nw4.novaworld.net/bhd_3_list.lob?page=2");

$regex = '~<td><b>(<font.*>)+\{a\.s\.u\}</font.*><font.*>sniper(</font>)+</b></td>.*<td><font.*>TDM</font></td>.*<td><font.*>(.*)</font></td>~iUs';
if (preg_match($regex, $html, $matches)); {
	array_shift($matches);
	$content .="<b>{a.s.u}Sniper</b>";
	$content .="<br>";
	$content .="<img src=http://asu-clan.info/html/serverstatus/onlineanim.gif>Server <font color=#FFFFFF>Online!</font>";
	$content .="<br>";
	$content .=" Current Players: <br><font color=#FFFFFF>$matches[2]</font>";
	$content .="<br>";
	$content .="Gametype: <font color=#FFFFFF>TDM</font>";
} else {
	$content .="<b>{a.s.u}Sniper</b>";
	$content .="<br>";
	$content .="<img src=http://asu-clan.info/html/serverstatus/offlineanim.gif>Server Offline";
}
?>

But this results in an error:
Parse error: syntax error, unexpected T_ELSE in /home/rsksquad/public_html/html/blocks/block-serverstatus.php on line 24

I cannot seem to use the else statement. Am I doing something wrong here or do I have to use a different statement ?

Sorry, another question,
I have 16 different images for 0-16 of 16 players. How can I use these? Say the Array returns 10 of 16, how can I make an image display? And a different image for every value that the Array returns ?
I tried using:

if ($matches[2]) = "1 of 16" {
		$content .="<img src=http://asu-clan.info/html/serverstatus/1p.bmp>";
	} elseif ($matches[2]) = "2 of 16"  {
		$content .="<img src=http://asu-clan.info/html/serverstatus/2p.bmp>";
	} elseif ($matches[2]) = "3 of 16" {
		$content .="<img src=http://asu-clan.info/html/serverstatus/3p.bmp>";

But this resulted in an error that I cannot use the '='.

How could I make this work ?

Thanks in advance,
VipleX

remove the ";" after your if() statement.

As for your second question, just do this:

preg_match('~([0-9]+).*of.*[0-9]+~iUs', $matches[2], $nums);
$num = $nums[1];
$content .= '<img src="http://asu-clan.info/html/serverstatus/' . $num . 'p.bmp"/>';

[VipleX]

Now the $num seems to stay at '1', but it does show an image though 🙂

I'm sorry, it now seems to work, I had to add " +[0-9] " into the first bit:

preg_match('~([0-9]+[0-9]+).*of.*[0-9]+~iUs', $matches[2], $nums);

bpat1434, Thanks for the help you gave me and the patience you had while helping me. Thanks a milion 🙂

[bpat1434]

Actually, you can just do:

preg_match('~([0-9]+) of [0-9]+~is', $matches[2], $nums);

The "+" modifier means "1 or more". The issue was the ".*" with the U modifier I believe. So the above works for me.

Glad I could be of help. If this thread is resolved, please mark it as such.
