[SOLVED] Explode Problem!

[bncplix]

Ok, so I am making something that will rip down a forum by parsing the thead IDS and the thread name.

 

So far I have it working to rip off the forum IDS and print them, then I use that forum ID to try and go back and parse again to get the thread ID. It will only get the first forum name and then stop

 

Here is the script:

<?php
$Site = file_get_contents('http://forum.tibia.com/forum/?subtopic=worldboards');
$boardArray[0] = "";
for ($i = 1; $i <= 74; $i += 1) { 
$splitA = explode('boardid=', $Site);
$splitB = explode('">',$splitA[$i]);
$boardArray[$i] = $splitB[0];
$splitC = explode('boardid='.$splitB[0].'">', $Site);
$splitD = explode('</a><br>',$splitC[$i]);
echo '<p> '.$i.'. '.$splitB[0].' - '.$splitD[0];
}
?>

 

Does anybody know why it only grabs the first forum name and stops? It works fine getting the IDS. Also, if i just do

echo 'boardid='.$boardArray[$i].'">'; It will print out excactly how it should split, so its not a mistake in that.

<?php
$Site = file_get_contents('http://forum.tibia.com/forum/?subtopic=worldboards');
$boardArray[0] = "";
$splitA = explode('</a><br><font class="ff_info">This board is for general discussions related to', $Site);
for ($i = 1; $i <= 74; $i++) {     
     $splitB=explode('<td bgcolor="#D4C0A1" class="ff_std">',$splitA[$i]);
     $forum=strip_tags($splitB[1]);
    echo "<br/>$forum \n";
}
?>

try this

try this

Thanks for trying, but nothing shows up now

I tried doing it bassed on the idea you had (splitting between <font class="ff_info">This board is for general discussions related to the game world) and it works!

List of board ids from that link:

$Site = file_get_contents('http://forum.tibia.com/forum/?subtopic=worldboards');
preg_match_all('~boardid=([^"]*)"~',$Site, $matches);
echo "<pre>"; print_r($matches[1]);

Woah thanks

 

Just one more thing I am having a problem with

I am now trying to get the thread IDS and the thread names from the actual sections, take here for an example:

http://forum.tibia.com/forum/?action=board&boardid=8527

 

But some of them say Page 1, page 2, etc and it keeps printing out that part

 

I am trying to make it just print the ID but it is also including this stuff:

2446049&pagenumber=1

 

So I used strpos to check if the & was there but it didnt seem to work (sometiems said it was there when it wasnt, sometimes said it wasnt there when it was)

 

Do you know how I can spit the topics up easily?

 

Thanks everybody im new to this

// example board. 
$board = file_get_contents('http://forum.tibia.com/forum/?action=board&boardid=8527');
preg_match_all('~threadid=(\d+)~',$board, $matches);
echo "<pre>"; print_r($matches[1]);

 

this will list all of the thread ids on the page.  Note however that since each page number is a link with the same thread id, you're going to have an element with the same id for every page number in the thread that is listed on the page.  If you don't want that, look into array_unique

[.josh]

Actually, didn't see that you also wanted thread names.

 

// example board
$board = file_get_contents('http://forum.tibia.com/forum/?action=board&boardid=8527');
preg_match_all('~threadid=(\d+?)"[^>]*>([^<]*)<~',$board, $matches);
echo "<pre>"; 
print_r($matches[1]); // <-- array of thread id's
print_r($matches[2]); // <-- array of thread names

 

Added bonus: this will NOT match the ids from each page number.

 

edit: changed the first capture to be non-greedy to make it more efficient

Thanks, got it working with array_unique!

Thanks for the help

 

 

Edit: Cool you posted again before I could reply. I mainly needed the thread IDS and I was going to be able to grab the titles myself, but thanks you saved me time.

 

Edit again: Woah this is weird, how do I print out specific indexes of these arrays? I never seen arrays setup like this where a single index contains all the data.

 

Say I only wanted to print out the second thread ID and thread name from the array, how would I do that? I know normally I just pass it the index number but this is different

[.josh]

echo $matches[1][0]; // echo out id of 1st thread
echo $matches[1][1]; // echo out id of 2nd thread
echo $matches[1][2]; // echo out id of 3nd thread
// etc...
echo $matches[2][0]; // echo out title of 1st thread
echo $matches[2][1]; // echo out title of 2nd thread
echo $matches[2][2]; // echo out title of 3nd thread
// etc...

 

If that's too much for you, you can do something like this:

 

$ids = $matches[1]; // your id array is now $ids so you can do for ex: $ids[1] for the 2nd id
$titles = $matches[2]; // your title array is now $titles so you can do for ex: $titles[1] for 2nd title

[bncplix]

echo $matches[1][0]; // echo out id of 1st thread
echo $matches[1][1]; // echo out id of 2nd thread
echo $matches[1][2]; // echo out id of 3nd thread
// etc...
echo $matches[2][0]; // echo out title of 1st thread
echo $matches[2][1]; // echo out title of 2nd thread
echo $matches[2][2]; // echo out title of 3nd thread
// etc...

 

If that's too much for you, you can do something like this:

 

$ids = $matches[1]; // your id array is now $ids so you can do for ex: $ids[1] for the 2nd id
$titles = $matches[2]; // your title array is now $titles so you can do for ex: $titles[1] for 2nd title

Yeah had just clicked reply then it said somebody already posted. I realized its a 2D array

 

Thanks, I will donate to the site soon
