fsock problem - please help!

[Steve Macleod]

Hi,

Im having a problem with an (apparently) simple little script, which is
designed to log on to a POP3 server and list the number of emails. I can log
in with username and password, and can relay the server echos back to the
page, but run into problems when I attempt to set up a while loop to read
more than one line of repsonse from the server.

My code looks like this:


fputs ($server_connec t, "LIST \n\n");

while (!feof($server_ connect)) {
echo fgets ($server_connec t,255);
echo "<br>";
}
fclose ($server_connec t);


$server_connect is an instance of the fsockopen() function. I keep getting
the appropirate output from this code, but only once the page has timed out!

Does anyone know how I could go about fixing this, so that I capture all
output from the server, but dont have to wait for a timeout to see the data.

Thanks.

First of all, there should be no space, and only one newline after LIST.
I don't know that the space hurts anything, but it doesn't belong there.

The server's responses end with a period by itself on a line. Check for
that instead of eof.

Actually, that's inaccurate. Multi-line responses end with a period by
itself. Some responses (to a STAT command, for example) are just one line.
For more info, refer to the POP3 RFC (if you haven't already):

ftp://ftp.rfc-editor.org/in-notes/rfc1939.txt

There's a great example POP session near the end of the document.

throw a call to flush() in there after the echos or turn
ob_implicit_flu sh() on so PHP will send what it has to the browser
instead of waiting for you to end the page.
