Filesize problem PHP problem

[The Tweet]

Hi,

Can someone help me with this problem?

Someone is submitting an URL.
The problem is that someone is submitting the URL per form. So it is allways something like http://www7.kinghost.com/amateur/the...mature/7/7.htm
In that case it is difficult to tell where to look, because the submitted URL is ending with htm.

I would like to know the filesizes of the jpg's in the URL, so I'm talking about matches 1 en 3. This is the script I wrote so far:

<?
$fp=fopen('http://www7.kinghost.com/amateur/thetweet/mature/7/7.htm','r');
$text=fread($fp,100000);
fclose($fp);
$preg='/
<a
[^>]*
href=
"?\'?
([^"\'>]*\.jpg)
[^>]*
>
([^<]|<(?!a))*
<img
[^>]*
src=
"?\'?
([^"\'>]*\.jpg)
[^>]*
>
([^<]|<(?!a))*
<\/a
/siUx';

preg_match_all($preg,$text,$matches);
for ($k=0;$k<count($matches[0]);$k++){
echo $matches[3][$k].' links to '.$matches[1][$k].'<br>';
}
?>
