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>';
?>

You may need to explain to the folk here what the above code is and isn't doing for you. What are you hoping for it to do, and what is it actually giving you?

<p><a href="http://www.searobin.co.uk/" title="of my website" onclick="javascript:window.open(this.href);return false;">Welcome - Robin Grady - SEAROBIN LTD - Offshore Construction and Subsea Intervention Specialist</a></p>

is this the result you expect the script to output???
if so, there is one change you need to do:

this is your line:
preg_match('/<meta name="description" content="(.*)">/i',$contents,$descriptions);

this is what it should be:
preg_match('/<meta name="description" content="(.*)" \/>/i',$contents,$descriptions);

notice the \/ at the end of the maching string.

o. one more thing,
your script initially gave me an error of not sendin header of the browser header, so i added
ini_set('user_agent','MSIE 4\.0b2;');
before the fopen command in order to fake some browser header id.

here is the code with my modification:
<?php
class ToolSet
{
      function createLink($url,$type)
      {
            $handle = $contents = $target = $description = $title = '';

            $target = (($type == 'external') ? ' onclick="javascript:window.open(this.href);return false;"' : '');

            ini_set('user_agent','MSIE 4\.0b2;');

            $handle = fopen(trim($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 $link;

echo '<p>'.$link.'</p>';
?>
it works fine.
remeber the results are not shown on the browser.
all that is output to the browser and is viewable by the user is:

right click the page and do "view sorce" for the code that is sent from the php script to the user's browser.
