fsockopen problem

pdstein · 10-24-1999, 10:45 PM

I was experimenting with getting HTML from another website by opening a socket and echoing each line. The strange thing is that while the echoed HTML looks nearly identical to the actual website, it seems to insert a few strange characters which screws up one image on the page. Does anyone know what is causing this?

The script is at http://www.ourchurch.com/misc/

The script is:

Code Sample:

 

<?

$hostname = &quot;www.cypressmeadows.org&quot;;

$port = 80;

$uri = &quot;/&quot;;

$showline = 0;



$fpread = fsockopen(&quot;$hostname&quot;, $port, &amp;$errno, &amp;$errstr);



if(!$fpread) {

     echo &quot;$errstr ($errno)

\n&quot;;

} else {

     fputs($fpread,&quot;GET $uri HTTP/1.1\nHOST: $hostname\n\n&quot;

     while(!feof($fpread)){

          $line=fgets($fpread, 255);

          if (!$showline) {

               $showline = ereg(&quot;<HEAD>&quot;, $line);

          }

          if ($showline) {

               echo &quot;$line&quot;;

          }

     }

}

fclose($fpread);

?>

Using this code produces a line of HTML that has the broken image in it

Code Sample:

                 <img src=&quot;

32

http://www.cypressmeadows.org/gif/menu/EmailUs.gif

d3c

&quot; border=0></A>

Where the actual website has no broken image:

Code Sample:

                 <img src=&quot;http://www.cypressmeadows.org/gif/menu/EmailUs.gif&quot; border=0></A>

I seem to have stumped everyone...

I'm not sure why you are looking for the first <HEAD> tag... are there lines before the <HEAD> tag that you are wanting to exclude? If so, you might want to use eregi() unless you know for a fact that the <HEAD> tag is all caps...

Other than that I don't really see a problem... you might want to try this instead though:

############
$page = file ("http://website.com&quot

;
for ($i = 0; $i < count($page); $i++) {
print "$page[$i]";

}
############

The file() function returns the file/web page in an array, then we walk through the array. Better yet, let's reduce this to one line:

############
print (join (file ("http://website.com&quot

, "&quot

);
############

This fetches the page into an array, joins it with "" (because the newlines are still attached), and prints it out.

I still am not sure why your code above doesn't work though - it looks pretty much normal to me - maybe try it without sending a HOST header? (I've never used the HOST header - I just send the GET and it works for me)...

Hope this helps.
