New Comment:
It seems that socket_set_blocking($fp,FALSE); results in other peculiar
behaviour.
When connecting to SMTP server, the server sends some data across the
socket right away, usually something identifying the server.
$fp = fsockopen("mail_server", 25);
var_dump(fgets($fp, 1024));
fclose($fp);
returns the server identify string
$fp = fsockopen("mail_server", 25);
socket_set_blocking($fp,FALSE);
var_dump(fgets($fp, 1024));
fclose($fp);
returns (false)
$fp = fsockopen("mail_server", 25);
sleep(1);
socket_set_blocking($fp,FALSE);
var_dump(fgets($fp, 1024));
fclose($fp);
returns identify string.
The position of the sleep() call can be after socket_set_blocking() as
well.

The following code doesn't work with php4.3.0
As foef() never returns true it got stuck in the while()-loop...
When running the same code in php4.2.3 it works as it should so it
seems like a 4.3.0 issue...
( feof() returns true in 4.2.3... )
The scenario consists of the script connecting to a host which
immediatly replies with a textstring; "OK", which in turn is printed
out...

// Open a socket and connects to the host
$fp = fsockopen ($myhost, $myport, $errno, $errstr, 30);
// check for valid filepointer
if (!$fp)
{
echo "$errstr ($errno)<br>\n";
}
else
{
// sets the socket to non-blocking
socket_set_blocking($fp,FALSE);
// read data from socket upto EOF in 128 byte chunks
while (!feof($fp)) // <= FAILS IN PHP 4.3.0!!!!!
{
$buffer .= fgets ($fp,128);
}
// closing socket
fclose ($fp);
// printing the buffer
print "Buffer:" . $buffer;
}
