[PHP3] getting info from a socket connection From: Adam Roderick (adam <email protected>)
Date: 07/13/98

Because php treats a file pointer pointing to a socket connection almost
the same way it treats a file pointer pointing to, say, a text file, I am
having trouble gathering the information I need from a socket connection.

1. I connect to a socket
        $fp = fsockopen($server, $portnumber);

2. I can use the fgets command to get the first line of the "file", which
is the buffer.
        fgets($fp, 200)
That gives me:
        +OK server.name.com POP3 3.3(20) w/IMAP2 client at Mon, 13 Jul 1998 10:19:05 -0500 (CDT)

But I cannot read any other lines in the "file", and using the fseek
command does not offset the number of bytes, but keeps the file pointer at
the first character of the file. And the example in the documentation:
---------------------------------------------------------
$fp = fsockopen("www.php.net", 80, &$errno, &$errstr);
                          if(!$fp) {
                                  echo "$errstr ($errno)<br>\n";
                          } else {
                                  while(!feof($fp)) {
                                          echo fgets($fp,128);
                                  }
                                  fclose($fp);
                          }
---------------------------------------------------------
I can't seem to get to work, no matter how much I work with it. I think
this problem is because in the while loop, the feof command looks for the
end of the file, but in a socket connection there is no end of file,
because the connection if always ready to send or retrieve data.

If anyone knows how I can get the data put out by the server when I am
using fsockopen(), please reply.

Thanks,
