Simple PHP Scraper

[sal002]

I need a quick and dirty PHP script written that scrapes the highest price for converting Bytecoin into BTC as posted here - http://exchange.bytecoin.in/.

Any takers?

[bitcoinator]

Should it consider amount of bte to be converted?

[sal002]

Nope - just get the price.  SImple scraper.

Sounds simple, I will do it.

<?php

$url = "http://exchange.bytecoin.in/";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

preg_match_all("|<[^>]+>(.*)</[^>]+>|U", $curl_scraped_page, $out);

echo "Max buy: " . $out[1][10] . "\n";

?>

Genius - can I send you a small tip?

[Chemicalbro]

Sure, if you like. Just note that if the page changes format (ie. more tags, etc get inserted before the buy price), that quick grab will break. You'd have to change the array number to match the change.

Oh, wow... Really genious... Here is my solution since I did it too:

Code:

<?php                                                                                                                                          
  function get_max_price_from_table($table){                                                                                                   
    $max_price = 0;                                                                                                                            
    $rows = $table->getElementsByTagName('tr');                                                                                                
    for ($i = 1; $i < $rows->length; $i++)                                                                                                     
      $max_price = max($rows->item($i)->getElementsByTagName('td')->item(0)->nodeValue, $max_price);                                           
    return $max_price;                                                                                                                         
  }                                                                                                                                            
                                                                                                                                               
  $html = file_get_contents("http://exchange.bytecoin.in/");                                                                                   
  $DOM = new DOMDocument;                                                                                                                      
  $DOM->loadHTML($html);                                                                                                                       
  $tables = $DOM->getElementsByTagName('table');                                                                                               
  echo get_max_price_from_table($tables->item(1));                                                                                             
?>

Good as well !

[Chemicalbro]

I'd actually go with his, mine is REALLY quick and dirty, his is a little less so :p

[sal002]

Thank you both - tips sent.

[bitcoinator]

Oh, wow, I am bitcoiner now, thanks!

Here's my version.  It's quicker because it avoids using the network at all:

Code:

<?php

print "We are in maintenance. Please come back later\n";

<?php

print "We are in maintenance. Please come back later\n";

+1 - well, it worked for a bit!

Still works for me. 

In the same series, here's a script that will tell you what time it is:

Code:

<?php

print "21:40:51\n";
