can you please check what is wrong with the code below.  I cannot get it to work.

<?php
class ToolSet()
{
      function createLink($url,$type)
      {
            $handle = $contents = $target = $description = $title = '';
            
            $target = (($type == 'external') ? ' onclick="javascript:window.open(this.href);return false;"' : '');
            
            $handle = fopen(trim($url),'r');
            
            $contents = fread($handle,700);
            
            fclose($handle);
      
            preg_match('/<title>(.*)<\/title>/i',$contents,$titles);
            
            preg_match('/<meta name="description" content="(.*)">/i',$contents,$descriptions);
            
            $title = $titles[1];
            
            $description = substr($descriptions[1],50);
            
            return '<a href="'.$url.'" title="'.trim($description).'"'.$target.'>'.trim($title).'</a>';
      }
}

$tools = new ToolSet();

$link = $tools->createLink('http://www.searobin.co.uk/','external');

echo '<p>'.$link.'</p>';
?>
