[SOLVED] Previous Question - Regular Expressions

[OLG]

Hey,

Approximately 2 years ago i asked a question on regular expressions, the topic is therefore archaeic and unrecoverable but contained the info i needed to solve my current problem.

 

<?php
$mycookies = GetCookies("www.site.com/login.php",
"usrname=user&password=pass&[email protected]&submit=LOGIN&set=Y","");
$opts = @array('http'=>array('method'=>"GET",
'header'=>"Accept-language: en\r\nCookie: ".$mycookies."\r\n" ));
$context = stream_context_create($opts);
$fp = fopen('http://www.site.com/statistics.php?id=2111292', 'r', false, $context);
fpassthru($fp);
$html = fread($fp, 1000000);
fclose($fp);
$strip = strip_tags($html);
echo $strip;

function PostPage($host,$query,$others=''){
   $path=explode('/',$host);
   $host=$path[0];
   unset($path[0]);
   $path='/'.(implode('/',$path));
$post="POST $path HTTP/1.1\r\nHost: $host\r\n";
$post.="Content-type: application/x-www-form-";
$post.="urlencoded\r\n${others}";
$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
   $h=fsockopen($host,80);
   fwrite($h,$post);
   for($a=0,$r='';!$a;){
       $b=fread($h,8192);
       $r.=$b;
       $a=(($b=='')?1:0);
   }
   fclose($h);
   return $r;
}
function GetCookies($host,$query,$others=''){
   $path=explode('/',$host);
   $host=$path[0];
   unset($path[0]);
   $crlf = "\r\n";
   $path='/'.(implode('/',$path));
   $post="POST $path HTTP/1.1\r\nHost: $host\r\n";
$post.="Content-type: application/x-www-form-urlencoded\r\n${others}";
$post.="User-Agent: Mozilla 4.0\r\nContent-length: ";
$post.=strlen($query)."\r\nConnection: close\r\n\r\n$query";
   $h=fsockopen($host,80);
   fwrite($h,$post);
   $r=""; 
   for($a=0;!$a;){
       $b=fread($h,512);
       echo $b;
       $r.=$b;
       $gotSession=strpos($r,"ASPSESSION");
   if($gotSession)
      if(strpos($r, $crlf . $crlf,$gotSession)>0) break;
       $a=(($b=='')?1:0);
   }
   fclose($h);
   $arr = split("Set-Cookie:",$r);
   $AllCookies="";$count=1;
   while ($count < count($arr)) {
$AllCookies.=substr($arr[$count].";",
0,strpos($arr[$count].";",";")+1);

$count++;}
   return $AllCookies;

}
?>

 

This is my current script - if i just run down what im doing here. I'm using fsock to establish a connection to a third party site and then submitting a set of details in order to login - i then strip the html tags away from the page that i've fopened and read.

 

What i now need is to use preg_match to extract the string "Rank: 999,999" for example and then split that down to 999,999 and then remove the comma - this is the part i am stuck on - i just really don't understand regular expressions.

 

Does anyone think they could help me out here and then explain it?

 

Thank You

Hi OLG. Neat scrape.

 

I'm not so good with RegEx either, but you can probably get what you want with explode() alone.

// after you've assign $html
$x= explode('Rank: ',$html,2);
if($x[1]) $y = explode(' ',$x[1],2);
$rank = str_replace(',','',$y[0]);

if(is_numeric($rank)) echo $rank;
else echo 'this didnt work after all..';

I don't think that worked

 

Additionally - i have now fixed the stripping issue (stupidly used fpassthru - now sorted) - however there is still some javascript in the result - so i need to remove that.

 

I'm fairly certain that it didn't - any other ideas?

 

Thanks for the help so far (that was very fast).
