New Comment:
The timeout parameter is the timeout for the connection setup. To set
a timeout for socket reads/writes, use the socket_set_timeout()
function.
I'm making this a documentation problem, because we don't make this
very clear.

I'm having trouble reading the data from responses over socket
connections.
For instance, this code (similar to that on the online docs for
fsockopen, example 1),
$fp = fsockopen ("localhost", 80, $errno, $errstr, 10);
if (!$fp) {
echo "$errstr ($errno)<br>\n";
} else {
fputs ($fp, "GET / HTTP/1.0\r\nHost: localhost\r\n\r\n");
while (!feof($fp)) {
echo fread ($fp,128);
}
fclose ($fp);
}
results in a timeout on the fread line (even if I let it run for 300
seconds). I also tried the udp example (example 2,
"fsocketopen("udp://127.0.0.1"...) on the documentation page and had
the same problem. Also note that the fourth parameter to the fsockopen
doesn't seem to be working in this case since this code took 300
seconds to timeout, not the 10 specified. The CPU usage by php went to
100% during the attempted excution of this code.
I have the same problem if I try using fopen to open a web page and
read the data (as in the below code). It always hangs on the fread or
fgets of the file pointer with the response in it. I know the remote
service (e.g., the web server) is actually sending a response string
because I can see it in the server log.
My hardware is a bit unusual. I'm running SuSe linux kernel
2.4.7-SuSe-SMP under VM on an IBM mainframe. I had these errors with
php versions 4.2.0, 4.1.2, and 4.0.6.
I tried to replicate the problem on an intel box with RedHat 7.2 kernel
2.4.9 and php 4.0.6, but failed. The most abnormal behaviour I could
find on that platform was that "fopen" and then "fread" of remote or
local web pages took *way* too long.
For instance, this code eventually got the desired response, but it
took about 20-24 seconds:
$fp = fopen("http://localhost/";, "r");
$text = fread($fp, 20);
fclose($fp);
echo $text;
If I used fsockopen (e.g., with the first piece of code above) on this
box it ran in less than a second and gave the expected response.
Any help is much appreciated. I really need to figure out how to read
data over sockets on that first machine.
Thanks,
Graham Warden

This is somewhat related to my previous bug post (#10996) about a year
ago.
